Land setup?

[Namio]

If I were to put a rock or something in do you think it would ever climb out of the water on to it?

The only time a Budgett's frog that will climb out of water is when you mimic the drying of the pond which triggers their instinct to find land in order to burrow down and estivate. If you provide them with normal/appropriate conditions they will never get out of water.

Can budgets frogs have land setups with water bowls.

That would not work. Imagine Budgett's frog as almost like a fish in the frog world. You would not want to put a fish in such setup, would you?
