I think making undertale into a bunch of different would give it more justice that are still connected in some way.

maybe all the bosses could be chess pieces to mirror how the two main bosses in deltarune are card themed.

You would play as frisk team member wise I think you would only get one

The ruins would take place in a old library.

I think it would have a more fantasy and lush vide but yet still feel barren

Toriel would be a queen piece, the queen of a forgot kingdom. The main boss

Asriel/flowey a pawn (it makes sense i swear), I think it would work if he isn’t a party member but more of a lancer character.

Nastablook a sheet music paper or a cassette player he would still appear in other locations.

For a secret boss I could be funny and make the small frog or even more funnier Toby.

Snowdin in a teen and young child’s room with a broken ac

Papyrus would be a rook, the royal guard would all be poker cards and would be in a type of gang.

Sans is a sock end of statement. Don’t how a chess piece and a sock became bother I don’t feel like explaining.

Monster kid is I have no idea but they would be permanent party member.

Grillby would be lighter that go snuck into the room

Secret boss wise i said mad mew mew

Waterfall a pool closet with broken pipes that makes the place flooded.

Undyne would be a knight (Ayo undyne the knight confirmed)

Gerson is a pool toy, would kinda be undyne mentor who now just sleeps in her castle or big ass house.

Nastablook two the sequel

Mad dummy would be replace since she’s now in snowdin by a battle crazed dummy in undyne old armor (their name is scraps)

Temmie is pool floaty so there is just one big temmie

Gaster/ mystery man would be the secret boss

Hotland takes place in a kitchen

Alphys would be a bishop (she would have no idea what a bishop does) still helps out frisk but she actually shows up in person more.

Mettaton is a Metta microwave or a radio but a microwave would be funnier so idk. Mettaton would take over the whole of hotland after frisk befriends alphy

Muffet would be a cook book with her spiders being stuff you would add on sweets, sprinkles, cake toppers over stuff, her pet spider would be a whole thing of frosting.

Btt the core is inside a oven

Burger pants is a burger warper.

So sorry would be the secret boss

New home don’t actually have an idea for this one

Asgore is a king piece

Asriel returns now he has been promoted to a queen

Chara would be the secret boss.
