A fish bowl wouldn't work because the suggies can't climb out of the glass. You would have a very frantic suggie who could become dehydrated.
Some suggie owners have used chinchilla bath houses for ball pits. It has
to be something they can climb out of. I purchased a large plastic food drainer from the Dollar Store and filled it with ping pong balls. I have placed mealies in there for them to "hunt" and also fleece strips to make bedding with. In the morning, all the fleece strips would be in their sleeping pouches and the ping pong balls are everywhere!!!
This isnt a toy to leave in their cage all the time because it gets dirty pretty quickly.
