Happy Pets: NEW! Guinea Pigs
Guinea Pigs, the cutest bundles of fuzzy love you've ever seen, have made their way into Happy Pets today. Unfortunately, each one is 54 Facebook Credits, which means you'll need to spend real cash (or $5.40 USD) to own one. And, like most pets, your ability to buy them depends on the level you've reached.
The Pink Guinea Pig, shown in the in-game window prompt above, is open to all levels. The other colors -- Heather, S'more (an awesome name for a pet color), Brick Red, and Charcoal are purchasable starting at Level 31. They each take two days to mature and share a feeding time of six hours, but they sell for different prices.
