A Banana is a food that restores 2 Hits. You can pick bananas from banana trees on Karamja. Each tree holds 5 bananas. Another way of obtaining bananas is to use the bones to bananas spell.
You can buy these at Wydin's Food Store, located in Port Sarim. You can also earn 30gp from filling a crate with 10 bananas on Karamja, after getting employment from Lathus.
The crate in the back room of Wydin's Food Store, which requires the use of a white apron to access, contains a banana. Searching the crate produces the following dialogues and system/chat messages:
- (Search crate)
- (there are bananas in the crate)
- (would you like a banana?)
- (you take a banana)
- (Banana is added to players inventory regardless of buckets already held)
