The Hamster Playground was a set released in 2010. It came with pets number #1888 and #1889. It was a set that used pegs and not magnets. It came with two apples, one red, one yellow, a shovel, carrots, a red fire hydrant, a cheese with an apple in it, and a green bowl. It also has a sphere that can be attached to the top and you can put your pets in it to roll them around. It also had a water bottle and a hamster wheel that you can put your pets on. The set also had a water bottle and a tube to "give treats to your pets," as said on the back of the box.
