Animal Breeder 2 on Game Boy is one of those weirdly addictive little pet sims where you end up way too invested in your pixel pets. You start with a couple of basic animals—maybe a dopey-looking puppy or a kitten that keeps glitching through walls—and suddenly it’s three hours later and you’re obsessively breeding them to get the rarest colors.

The sprites are janky in that classic Game Boy way, but there’s something charming about watching your creatures grow from blobs into slightly more detailed blobs. Some of the breeding combos make zero sense (why does a green cat + a spotted dog give you a purple rabbit?), but figuring it out is half the fun. Just don’t get too attached—accidentally feeding them the wrong thing turns them into little ghost sprites, which is equal parts hilarious and tragic.

It’s the kind of game you play with one eye on the TV, muttering “c’mon, just give me the striped one this time” while mashing buttons. If you’ve got a soft spot for old-school jank and virtual pet chaos, this’ll suck you right in.
