Angry Birds was really all about the characters. What other animal characters do you think can be likable enough to be a hit mobile game?
Angry sperm. Spunk all over the place and some dude in a wheelchair throwing rubber jonnies like wind socks gliding through the air neutralising them.
personally, i think piggies are really cute, and i've been waiting for one good iOS game that features them. but maybe that's just me.
Somehow "Angry Cephalopods" just doesn't roll off the tongue so well. Angry Squids, perhaps? Squids are downright mean critters, but are easy to draw cute, and are delicious when fried or grilled.
Angry Mastodon? Angry Cheetah? Or, if we can step aside from the animal kingdom, how about Angry Leprechaun?
Rather than trying to hurt the green piggies, let's try to catch the angry bird's eggs. Switch it around and make it a little different. Angry Birds 2: Pigs Fly High
Why does everyone/everything have to be so angry? How about Happy Squirrels, Slightly Annoyed Fish, Bored Wombats, Confused Badgers etc.?
