This is a little cupcake with blue frosting. The sprinkles spell out "EAT ME", which is a little surprising, but not as much as if it'd said "UP YOURS".
Type: potion Selling Price: 30 Meat. Effect: Cupcake of Choice (20 Adventures)+30% Item Drops from Monsters
You eat the blue-frosted astral cupcake. You immediately get a tingling sensation in your feet, and begin walking without rhythm so that you won't attract the worm.
Your stomach is still a little queasy from digesting a cupcake that may or may not exist in this dimension. You really don't feel like eating another one just now.
References
"Walking without rhythm so you won't attract the worm" was originally a reference to Frank Herbert'sDune, in which the Fremen traverse the sand on Arrakis with no apparent rhythm so the sandworms don't know they're present.
"Walking without rhythm so you won't attract the worm" and "Cupcake of Choice" are references to Fatboy Slim's "Weapon of Choice" (which reuses the phrase from Dune).
