Behavior for the 1.19 Swamp (generic) Frogs

Many species of frogs burrow into sand, soil, or mud for a variety of reasons, like hibernating in mud at the bottom of ponds in the winter. It would be cool if in-game swamp frogs could dig into mud blocks as well. They would burrow into the block when scared or when they're not doing any other activity, and perhaps a small indicator that the frog is in the block would be visible (maybe eyes sticking out of it). If a player breaks the block without Silk Touch, the frog comes out, and if it's broken with Silk Touch the block with the frog in it drops as an item. When the frog leaves the block, it leaves behind Silt, which is like a carpet variant of mud and can be used to brew Thick Potions. Alternatively, 1 Silt can be combined with 1 Snowball to make it into a Mudball, which deals half a heart of damage to whatever it hits.
