It is presumably vanilla ice cream with 3 bananas topped with cherries for arms, chocolate sauce for hair, 3 chocolate buttons for eyes and a big smile which is is made out of licorice.
SpongeBob and Patrick were eating them very quickly and rapidly, which caused them to get a big ice-cream headache - "hangover". All the mess that SpongeBob and Patrick made flew onto the Goofy Goober waiter.
- This may be SpongeBob and Patrick's favorite ice cream of all time.
- It was mentioned in The Clash of Triton by SpongeBob, however, he mentioned it as "Gooberry", not "Gooberberry". Harold also asked for one at the ice cream shop in Porous Pockets. However, he asked for extra nuts, and there are zero on the sundae. However, it is possible that the nuts are either optional or inside the sundae.
