The Disney ones are cute. And in what other line have so many characters been lovingly well represented?!
They're a gumball type machine that I imagine many parents keep around as a reward system for chores and good behavior. The toys should be slightly obscured to retain a surprise factor, but one in every pack is blind. Capsule toys aren't huge here like they are elsewhere{cough-Japan-cough} so it's pretty neat to see this gashapon-esque toy line getting so much positive feedback. The dispensers are adorable and take fake coins that are included with each machine or actual money(pennies and dimes) though feedback on the quality isn't so positive.
I researched these for my cat, Grim, cuz he loves them. They looked like they'd bounce so I got the cheapest 3 pack I could find. One of the capsules had a rubbery ring you can put a squinkie on.
The rest are mostly ugly and make great cat toys. Always supervise your kitty with any new toy. Some cats will eat things they shouldn't(like electrical cords, plastic bags, and rubber) abd even cat toys(intended for cats) can be unsafe or become unsafe in the paws of a kitty.
Only one of my four cats cares about Squinkies, but he's NUTS for them;D they bounce all over like crazy.
