Shampoo is a hair care product and drink that only appears in the episode "Bubble Buddy."
It is an orange bottle of shampoo and was drank by Bubble Buddy in the episode of the same name. SpongeBob said that the shampoo tasted funny and when Squidward tasted it, he called himself silly saying he got the "diet shampoo." Squidward brings out the regular shampoo and then SpongeBob asked if Bubble Buddy could also have a bendy straw. Squidward just bent it down the middle and stuck the straw in Bubby Buddy's "mouth."
- "Diet Shampoo" is also available.
- The straw didn't pop Bubble Buddy, but a needle would.
