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 red message in the chatbox will state You have a funny feeling like you're being followed.
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.
