Artist Tea Wei turns popular characters into visions of dissection in these illustrated cartoon GIFs. The motioned images start off as squared characters and slowly expand into separated body pieces to reveal what's going on inside of them.
It's highly unusual that a sponge would have inside organs, but according to Tea Wei's illustrations, SpongeBob SquarePants' has his own type of digestive track. Though it sounds like a gruesome depiction, the illustrations are actually very vibrantly colored and creative. Expect to see a lot of yellow, blue and orange colored guts; apparently, these cartoons lack any other important organs.
GIFs have been extremely popular in the form of videos, but now I'm sure you will run into more illustrated ones like Wei's on the Web.
