Tbh these arent DEATHS. These are Just poses

something i noticed is that the pizzice's death sprite resembles a decoration from the grinch demo

MEAT DETECTED

Also, a few other references I could spot:
-The Sausage Clerk, Pizza Slug, and Mushroom Patroller death sprites are based on enemies for a scrapped game called Pizza Horror, with them being the Sausage Master, Pizza Bandit, and Gazing Shroom respectively.
-The Eggplant Farmer death sprite is not only based on Tail, but is actually a fusion of Tail, Shadow Snick, and the early/placeholder design for Electric Potatoes.
-The Tribe Cheese death sprite having a pizza cutter in its forehead is a reference to a scrapped behavior for Tribe Cheese, where they would wield a pizza cutter.
-The fact that the Peppibot death sprite has them vomiting cheese is of course a reference to a scrapped idle animation for Peppino, but it could be a reference to Cheese Peppibots, a scrapped variation that would spit cheese balls to give the player the Sticky Cheese transformation.
-The Pickle death sprite could be a reference to the Roper enemy from Memoirs of Magic, which is what the Pickle is based off of.
-The Pineacool death sprite is both a reference to a background decoration from the Noise's Hardoween demo and a scrapped Pineapple Biker enemy, which would drive after the player on a bike.

I assume that the Pizza Box Goblin's death sprite is a reference to Gabriel, right?
Not sure if that really is his name, but it's what it says on the PT wiki, so I'll just say that.

why does pencer's look like rayman

@PlushMario64: yes

is tail supposed to be the eggplant guy?

@funny words magic man
that's for Kentucky Kenny. it's a reference to a Mr. Pinch unused sprite

What is the boots one for?

Here are all of the references i could tell from the sprites

Fun fact: mini John was inspired by something PTG Made on a stream

@Greenstachio the gustavo sprite is for Bad Rat and the orange frog sprite is for U.F.Olive

The Peppibot sprite is my favorite. Also what is the Gustavo one supposed to be?

such a cool idea

Basically the idea behind this was that these enemies would do this if you managed to dash into them twice in a row, resulting in blink-and-you'll-miss-it sprites
