I shop at an Asian grocery store sometimes, and the containers they sell those in make awesome toys. I'll get a pic to show you what I mean but after you empty out the jellies the container is usually made into a bank but glider owners make them into hidey toys.
um as far the jellies, they are kinda gross
I opened one one day and offered some to my guys they licked it a couple times but didn't like it. It isn't something I'd give them very often even if they did like it. They jellies come in a huge variety but again I mainly buy them for the container they are usually like 5 bucks
