Strange game. I've never played it, but I just sorta happened across this-It's basically a sort of "defense" game, where you defeat the enemies to keep them from destroying a pile of food at the end of the stage. Your character can call allies to help out. In both Garfield's Defense games, Arlene functions as the team Medic. When you summon her, she blows kisses to heal things.

Also, apparently Liz is in the second one? I've yet to see what she's supposed to do...
