This is my favorite small toy! It's really strong for its size.It takes 3 AAs.It has a really cool vibration pattern.you don't really get to choose one.It doesn't have a buttons just one of those wheel thingies.lol.it's a has a really cool vibration pattern.it's hard plastic.Usually that bothers me, but the vibration makes up for it.The controller is really cute.it is glittery and when you turn in on, it lights up with rainbow colors! there's a little shadow couple on there too lol.really cute.
