My baby tiels LOVE to take things apart. Their food dishes are plastic with plastic hooks that hold them to the cage bars. They have figured out how to get the food dishes off the cage and THEN get the plastic hooks out of the food dish

. They will also spend hours a day chewing on every connector for every toy they have, trying to get them off the cage and have figured out how to get the bells off of a couple of their toys. Does anyone have any ideas for "take apart" toys for tiels?

I know there are a lot of great toys for larger birds but I haven't seen anything that is tiel appropriate.
