Kelp Milk is a brand of milk that is sold in Bikini Bottom. It can be seen in SpongeBob's fridge if you look closely in the episode "Procrastination." It is possible that it could be also a type of Kelp Cream.
Kelp Milk appears to be in a small carton of milk that is white/pink, and red in color. The text is written in red. On the side of the carton is a picture of what looks like kelp.
- Kelp-Milk is the second type of milk shown in the series. The first is Snail Milk. However, Kelp-Milk isn't showed as often as Snail Milk.
- Kelp-Milk is also sold at Barg'N-Mart.
