Yargle

Yargle is a gluttonous Frog Spirit that haunts Dominarian Urborg.

History
Belzenlok's lieutenant Yar-Kul became too ambitious and was transformed into a maggot by the demon lord. That maggot was eaten by a frog, which later grew into Yargle.

Yargle was the first defense of the Stronghold when the Skyship Weatherlight attacked the Cabal. Muldrotha took him out.
