Goliath Frogs are a large enemy uncommonly found in the Sunken City.
Behavior
The Goliath Frog is entirely stationary, and the main danger it poses are armies of regular Frogs out of its mouth.
It is not very dangerous by itself due to its immobility, but it will periodically spit out regular Frogs and can eat the Spelunker if they get too close to it's mouth. There is no limit to the number of frogs it can produce, but it will not spawn more than a certain number at once.[Needs Research]
Strategy
It is easiest to kill the Goliath Frog by throwing a sticky bomb at it from a distance, which will kill it along with any nearby frogs it spawned.
