If so, you might want to nab one of the Pikmin crochet patterns that are currently being sold (for $5 each, here) via Annie Johansson's (aka Liebe9's) etsy shop.
Here's what the final products look like, by the way. Aren't they adorable? I think I like the Dumbo-esque yellow Pikmin the best, although all three of them are so cute I could puke.
I don't know a "chain stitch" from a "single crochet," so I'd personally prefer it if Johansson sold completed crocheted Pikmin characters, but I can understand why she doesn't.
Johansson does sell "already made" Ocarina of Time amigurumis (for $35, buy one here), though, so if you just have to own some sort of game-related craft, they're probably your best bet for the time being.
