It comes in a gag can that has an orange label, which depicts a picture of a peanut within a brown square in the middle. Above and below this, the words "seanut" and "brittle" respectively are transcribed in purple letters.
Upon opening the can, purple tubes will shoot out as a prank.
Role in episode
When outside of the Palace of Pranks, introducing the store to him, SpongeBob informs Patrick that he got a can of gag Seanut Brittle from there. Patrick, overwhelmed, attempts to open the can to taste its contents. However, SpongeBob warns him that it is a booby trap, but Patrick blows him off, only for him to be pranked as purple tubes shoot out of the can.
When inside the Palace of Pranks, Patrick, despite having been pranked by it the first time, finds gag cans of Seanut Brittle in the store and once again opens one of them to taste the contents, once again being pranked as purple tubes shoot out. Off-screen, Patrick berates himself for falling for it again.
- The product itself is a parody of peanut brittle, while SpongeBob's Seanut Brittle gag can is a parody of the snake nut can prank.
