Wilf

Wilf, along with Rachel, Marv, Hank and Sarah, may be encountered during a Temple trek or Burgh de Rott Ramble. The challenge involves quickly feeding them. If Wilf is left without food for too long he begins to resemble a ghast before eventually turning into one. If this happens, the ghast must be killed.

He can be fed almost any normal cooked food, but in case you don't have any, you can kill the nearby snails and cook them for him to eat.
