Toby Fox masterfully puts love and care into every part of Undertale, and with Deltarune, he also loves hiding things for fans to hunt out. From secret routes to hard bosses, every little thing is worth paying attention to as anything could lead to a secret.

These video games are not only great, but they have some of the most emotional and resonating stories and characters in the medium.
Chapter three of Deltarune introduced some wonderful characters themed around the Dreemurr family’s living room and takes the Delta Warriors onto a fantastical set in front of a live Darkner audience. Mr “Ant” Tenna is hiding plenty behind the scenes of his TV Time game show, and this Dark World has plenty for you to discover.
Story, boss and ending spoilers for chapter three ahead!

Ball Machine Rewards
Gacha Games Have Nothing On These
If you manage to achieve a B-Rank or better in either of the two rounds of TV Time, you are granted access to the B-Rank room, which contains one of modern gamers’ biggest weaknesses, a gachapon machine. This photo-realistic machine allows you to spend your hard-earned points on questionable rewards, and some of these are silly.
With different tiers of rarities, you may spend all your points only to get some TV Dinners and Revive Mints in return. If you are lucky enough, you can win something as wonderful as a golden Tenna statue. Other potential prizes include Lancer himself, not a statue. Lancer can be obtained an infinite number of times, allowing you to fill up your Key Items with as many Lancers as your heart desires.

No Escape From The Watercooler
No Mercy
After the second green room, you must sneak your way backstage through a stealth section as you try and escape Tenna and his not-so-willing crew. During this, you can enter a room with an innocent-looking Watercooler. When interacted with, it starts one of the silliest battles in Deltarune and even Undertale.
If, instead of fighting, you leave the room, you will notice two more Watercoolers outside blocking your path, and re-entering, more will also be inside. They will continue to move and grow in numbers as you enter and exit until you are completely blocked from both the entrance and exit. Unless you initiate the battle inside the room, you cannot leave, meaning it’s “bable” or be “bobled” in this scenario.

Name Easter Eggs
Not Appropriate For Live TV
After being introduced to Mr. Tenna’s wonderful TV Time, the party is asked to input their contestant names from three letters, and we, of course, have to try entering rude words. Well, some name choices have unique dialogue for cases where you do enter specific names, such as inputting “BUT” or “TIT” makes Susie laugh and embarrass Ralsei.

The Best Tracks On Undertale’s OST, Ranked
The Undertale OST has some amazing music on it, here’s the very best.
One thing is that the game is coded to remove certain letters if other letters have been chosen to prevent the player from being able to input bad words. However, if you modify the game to give you the letters back, there is a special cutscene coded in where Tenna cuts to a technical difficulties screen before cutting back and setting your name to “FUN” instead.
Here are all the unique names that can be inputted to provide different dialogue:
KRS, KRI, RAL, SUS, AAA, PEE, POO, ASS, TIT, BUM, BUT

The T-Rank And Z-Rank Rooms
Perfectly Good Or Perfectly Bad
Each of the TV Time rounds has you doing your best to play well in a large variety of minigames to earn a good score and achieve a good rank. You are rewarded for getting each rank with more rooms being open for you to enter, and so you are highly encouraged to do well so as not to miss anything lurking behind the rank doors.
The highest rank is the T-Rank, which requires near perfection, but it’s purely cosmetic. At least that’s what the game tells you, but left of the ABC doors is a T-Rank room that has Tenna on a screen doing various poses. The Z-Rank also grants you access to a special room, which has some extra lore and a manhole that takes you to the console from the S-Rank room.

Beating The Monster Movie Minigame
What An Annoying Dog…
Upon entering the A-Rank exclusive room, you will get the option to replay the minigames from each round of TV Time as well as pay points to a Pippin to unlock a secret extra game. The Monster Movie minigame involves moving Susie around to protect a golden Tenna statue from many Shadowguys trying to destroy it.
If you actually manage to keep the Tenna statue alive after the barrage of enemies, then a familiar white dog attached to a rope will swing in and decimate it anyway, ending the minigame. This little dog is a representation of Toby Fox himself intervening on your playthrough for a wacky joke, quickly making your hard work protecting the statue crumble to dust.

Bonus Zone Pipis Room
Big Shot Partners
After beating the Lightners Live minigame, you will come across some rooms filled with TV screens all over, and in one in particular, you can find green screens with Tenna faces on them. If you interact with the one located in the bottom left, you will make your way into the Bonus Zone, where Tenna stores all the prizes for the show.

If you walk to the right in this room, you will find a suspicious closet that contains a singular Pipis. This can trigger one of two cutscenes with Tenna, depending on if you do or don’t have the Dealmaker or Puppet Scarf. If you don’t have them, Tenna will react in shock to an audience shaming him for the Pipis. The most interesting cutscene happens if you do have them, as Spamton will appear, and Tenna acts in shock.

Beating The Roaring Knight Boss
The Impossible Final Boss Is Possible
This boss strikes down our beloved TV host Tenna at the very climax of the chapter and initiates a battle against the party, and it does not go easily for you. The Roaring Knight is easily the hardest boss in the game, with ridiculously wild attack patterns and the ability to down Ralsei and Susie to negative 999 HP when they hit zero HP.
Despite this, the Roaring Knight fight is beatable, even though you only get one chance at it. Obtaining the secret Shadow Mantle armor earlier in the chapter makes its attacks do much less to whoever wears it, making things a little easier. After the “victory” of the battle, it will drop one of the important Shadow Crystal items, which will likely be necessary for a secret in the final chapters of the game.

Spending 1,225 Points On The Ball Machine
The Lost Girl
In the B-Rank room, you can find the Ball Machine, where you can gamble your points away for various items. You can put more points to increase your chance of getting something good, and if you try to use 1,225 points at once, you will be able to enter the machine itself. This then takes you into a strange maze where you can find a blue Ball Machine which dispenses a triangular-shaped object with some eerie dialogue.
With the number 1,225 being closely linked to Dess, the triangular object you get from the blue gachapon machine is likely her guitar pick, and this is just one of many small hints towards her strange connection to the story. There are plenty of hints towards Dess in both chapters three and four, so hopefully, we may start getting more concrete answers as to what happened to her.

The Egg
The Definition Of An Easter Egg
In each chapter, one of the most secret things is always the Eggs. These literal Easter eggs are super hard to find and will require guides. However, so far they do nothing and likely will not serve any major role due to how the casual player would rarely even find one of them.

In chapter three, the Egg is found by selecting specific dialogue options when being confronted by a Zapper. This will then take you to complete a console puzzle with a Bibliox to earn an item that you can then use to flee from a battle with a Ribbick. All of these strange steps warps Kris to a strange room with an Egg tree, and, once again, selecting specific dialogue options with the man behind the tree finally grants you the Egg.
If you missed out on any of the Eggs, do not worry, as they are purely collectible items as of chapter four.

The Shadow Mantle Secret Boss
The Final Console Showdown
As per usual, there is a cryptic secret boss found within this chapter that requires multiple steps to reach. Each part requires you to enter the S-Rank changing room in each green room area and play the odd console, obtaining the relevant key from each one. By completing all of these and then entering the third green room, you will be greeted by another console that ends with a secret boss within the game.
You can access the S-Rank green room for free if you achieve a T, S, or Z-Rank, and you can also buy an S-Rank from the seller Pippin, in the room south of the green room for 1,500 points.
Your reward for defeating the boss is the Shadow Mantle armor, a powerful armor that reduces damage from Dark and Star attacks. This is useful for the Roaring Knight boss fight, as it works wonders to reduce its ludicrous damage, making it a lot easier. This armor is likely very important, as it has been mentioned before, and considering the Roaring Knight drops one of the important Shadow Crystals, this is well worth doing.
