Max and Kevin are in day care. Max's nickname is Kicker. Max thinks Kevin's crutches are cool.
Max is now older and his grandpa built him a bedroom. His bedroom is under their house and can go outside and upstairs just from his room. His room is called the down under.
Now Kevin has moved in next to Max. Kevin is playing in his backyard with a ornithopter, when Max comes over because he sees Kevin is struggling to get the ornithopter out of the tree. Then Max helps Kevin get it down.
