The Youngllef is a pet received from the reward chest in The Gauntlet. It is a smaller version of the Crystalline Hunllef. Upon completion of the Corrupted Gauntlet, players unlock the right click "Metamorphosis" option to change between the regular Youngllef and the corrupted Youngllef variant. The pet will always be received in the regular form, even if it is obtained from the Corrupted Gauntlet.
When a player receives the pet, it will automatically try to appear as their follower. At the same time, a 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; it must instead be claimed from Probita in East Ardougne for a reclaim token, which costs 1,000,000 coins.
On death, if a player loses their pet (as a follower or in your inventory) it will wander around the area for 30 seconds before despawning. Even if the player returns in time, the pet cannot be picked up, and can be reclaimed from Probita for a reclaim token.
