I am not stupid this has way too much evidence. the character in smg4 known as mr.puzzles has made people insane such as smg4 in the gotta be perfect arc at the start of 2023. a similar character known as tenna (yes its tenna look at the link DELETE THIS ! (deltarune.com)) is that damn boob tube and in smg4 bob is searching for THE BOOB CHANNEL you know what this means right........ and in the boss fight at the end of the puzzlevision movie you know what song plays.... save the world from the hit 2015 rpg game undertale by toby fox who also made deltarune..... huh? now lets anylise mr puzzles who is a tv producer (he kind of reminds me of metaton for some reason) SMG4 Movie: PUZZLEVISION (MR PUZZLES SONG - CREATIVE CONTROL) (youtube.com) now if you look at this song you can see mr puzzles is a man with a tv as his head which is what tenna is believed to be.... what?

ok there is more in the song i just linked to. the song starts with ness from earthbound representing mr puzzles and if you do not know already ness from earthbound is actually sans from undertale. i have evidence for that as well (but its not official) i might link to that once im done here

he is also obsessed with getting high ratings like metaton a bit later there is the line..... I CAN DO ANYTHING you know what that means don't you that means he is connected to the hit charater from toby fox's deltarune JEVIL..... who is a secret boss connected to spamton (in which spamton is heavily connected to tenna) then he says lets seal the deal this is a massive lore drop because spamton and tenna had a deal where they went on the phone and always talked to each other until they didn't ig.

mr puzzles is insane and who else is insane all of the deltarune secret bosses.

in conclusion mr puzzles is tenna therefore he is the main antagonist or secret boss of deltarune chapter 3.
