How can I combine abby caddaby and elmo?

i'm planning a birthday party for my niece and she loves these characters but one is pink and the other is red. PLEASE give me ideas!!!!|||You can combine them by making a poster for her birthday ( your niece must be in the center and beside her are abby caddaby and elmo.) For the balloons you can buy some of it (one must have a design of elmo and one must have a design of abby caddaby.)
