Giant mangrove frogs

Giant mangrove frogs are the size of Giant slimes, and they of course can eat bigger slimes and magma cubes. But they are absolutely lazy and spend most of their time sleeping under mangrove roots as a way to conserve energy, they would "taste" mobs that comes near them but spits them back out if their not slimes/magma cubes. Mobs that where tasted and spat out would not be dealt damage, but they would run away due to fear or discuss.

I don't think they need different variants like the other frogs, I was thinking they would only be mud colored to blend in the mangrove swamps.
