Pop On Pals Amusement Park Play Set is definitely a hit in my home (aff). The Pop On Pals allow you to be anything you want — you just pop on the mix and match rings and you can become a musician, a firefighter, a baker, or even a ballerina. The age for this is 2 (aff)-4 which I think is about right. My only complaint is that it only comes with one figure, so if you have more than one kid, you'll have some arguing on your hands! The pals themselves are the perfect size. They are big enough that they aren't a choking hazard, but small enough that your little one can hold onto them with ease. The lights and sounds definitely keep your kids interested in it.
After getting your hands on your first set, you'll be heading back to the store to pick up the add on sets. There is the Pop On Pals Pet Pack, Pop On Pals Pal Pack, Pop On Pals Ring Deluxe Ring Pack, Pop On Pals 2 (aff) n 1 Vehicle Set, Pop On Pals Pop and Go Airplane, and Pop On Pals Pop and Go School Bus. These can be purchased at Toys R Us, Target, Kmart, and Sears.
This will make a great gift for any little on you may have in your life!
