As the name suggests, this one is a Penguin pet. Penguin-Keeper on Tamatalk has run this one here: https://www.tamatalk.com/threads/penguin-keepers-zoo.194908/post-3354005
It has separate meters for each of the food and drinks, but the happiness indicator is shown in a separate meter via apple icons. He starts with one game as a young bird and will unlock more as he gets older. Penguin-Keeper says its similar in programming to the Gyaoppi pets, but I’m not sure that it’s a complete clone. The overall opinion was that the pet itself is frustrating and bad, though I wonder if having the instructions handy would have made this better, because it seems like a number of its functions are really unintuitive.
