Açaí

Seasonal Event
Açaí is a Karamjan delicacy, which heals 50 life points. It can be obtained from Guarani at Musa Point for 1 coin each. At 0.02 coins per LP healed, it is one of the cheapest foods in terms of coins to LP. For now, they have no further use other than a cheap food option. This can be useful for free players training at the Karamja Volcano for those who do not have access to lobster or swordfish fishing, or just simply to save some time from fishing. When eaten, the player recieves the message "Once you finish eating the açaí, the bowl magically returns to Guarani. Recycling the bowl avoids waste and helps to save the rainforest." in the chat box.

Introduced in an update on 15 February 2011 as follows -- "In other news... An exotic delicacy awaits you near a banana plantation..."

When questioned by several members on the official forums, Mod Timbo had this to say about the fruit:

Mod Mark then confirmed this on Wednesday afternoon GMT, in MoD MMG's clan chat by saying it will be used for future events in other languages, similar to Lily of the Valley, and Oktoberfest pretzels. This will most likely be referring to a Earth Day.

Trivia

 * Açaí is based on the real-life Açaí palm tree fruit. The trees bear berries similarly coloured to Açaí. These berries are known to be extremely healthy, and a good source of energy.
 * The bowl's colours are a reference to the Brazilian flag, which has the Açaí as a local sweet. Also, if one looks in the lower left corner of the image, they can see something that looks similar to a piece of the symbol in the Brazilian flag.
 * The rainforest spoken about is likely based on the Amazonic Rainforest, the largest one in the world.
 * Guaraní is a tribe native to South America.
 * If a Ghast eats your Açaí, the bowl will not disappear, instead it will stay in your inventory as any other bowl.
