Shampoo is a hair care product and drink that appears in the episode "Bubble Buddy."
It is a light orange bottle of shampoo with a white bendy straw.
Role in episode
SpongeBob says that the shampoo tastes funny, and 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 the bubble's "mouth."
"Diet Shampoo" is also available.
For some reason, the straw did not pop Bubble Buddy.
