Shampoo is a hair care product and beverage that only appears in the episode "Bubble Buddy."
Shampoo comes in a light orange bottle with a white bendy straw.
Role in episode
This is the drink that SpongeBob orders for Bubble Buddy when they go to the Krusty Krab. SpongeBob says that the shampoo tastes funny. When Squidward tastes it, he calls himself silly, saying he got the "diet shampoo."
Squidward then brings out the regular shampoo and SpongeBob asks if Bubble Buddy could also have a bendy straw. Squidward then bends it down the middle and sticks the straw in Bubble Buddy's "mouth."
For some reason, the straw does not pop Bubble Buddy.
