Actually, this might be a large roadblock. A really, really large roadblock.
Bandai actually has announced a very large Snorlax plush. At nearly 5 feet tall, it's not actually life size but it is absolutely huge. Of course, it also costs the equivelant of $450 and is exclusive to Bandai Japan's online webshop. So maybe it's best to take a cue from Snorlax and keep this one in your dreams.
