Olmlet is a pet obtained from the Chambers of Xeric. It is a much smaller version of the Great Olm, with its body fully visible. Players have a 1/65 chance of receiving the pet when they receive a unique drop (broadcasted rewards) after defeating the Great Olm.
When a player receives the pet, it will automatically try to appear as their follower. At the same time, a red message in the chatbox will state You have a funny feeling like you’re being followed.
However, if a player receives a pet while having a follower out (for example, a cat), it will be placed into their inventory. When this occurs, the message in the chatbox will instead state You feel something weird sneaking into your backpack. If a players inventory is full and they have a follower already, they will not receive the pet.
On death, if a player loses their pet (as a follower or in your inventory) it will wander around for 30 seconds before disappearing completely.
Players can pay a one-time fee of 500,000 coins to Probita in East Ardougne to have this pet insured. Should the pet be lost while insured, it can be reclaimed for 1,000,000 coins.
The olmlet is able to metamorphose into five other pets. For the olmlet to be able to do so, players must use metamorphic dust on their olmlet, which can only be obtained from completing a Challenge Mode raid within the Chambers of Xeric. Once players do so, the olmlet can metamorphose into one of the following five pets:
