Not everyone will get this but I'm coming to make a statement

What about ‘O’ Chunks?

Okay. Maybe Toby Fox didn't get all his ideas from super paper Mario, but in Deltarune, you fight a jester who has a purple and black colour scheme in the final area.

Well actually super paper Mario took inspiration from undertale

Super Paper Mario was released in 2007. Undertale was released in 2015. Check your facts.

The underchomp fight in the underwear took inspiration from undertale

Also the Underchomp fight took inspiration from an SNES game called Earthbound which was another major inspiration for Toby Fox. Fact check yourself before you make yourself look like an idiot

Yeah it was either that or earthbound I thought
