How do you feed the chuzzle?

You have to buy food from the shop. The chuzzle will eat when it's hungry, but you can't feed it yourself.

Once it's added to the chuzzlearium- as long as there is bowls of food available it will eat when it's hungry. You have to purchase food bowls from the shop.

Once you are inside your chuzzlearium, there is a "shop" button in lower left corner.

Tap it, then tap food.

Then depending on how many coins you want to spend pick a bowl.

NOTE: It's best to have several bowls of food in the chuzzlearium. If they should ever run out of food- only the food will need refilling. The bowls you purchased originally will always stay even if they run empty.
