Apparently, someone over at Disney decided it would be a great idea to make all their characters in the shape of mutated hamsters. Tsums Tsums come as stuffed animal versions and as vinyl toys. Both sets come in various sizes so you can stack them. Really. On paper, the idea sounds ridiculous. In reality, these things are selling like hotcakes.
I picked up vinyl versions of Goofy and Perry (of Phineas and Ferb fame) because the small ones are close in scale to the Fighter Pods. I must admit that they are oddly appealing and I may pick up a few here and there. A new Marvel vinyl set is currently hitting stores as well.
