That is soooooooooooo cute!
Find a pink baseball cap and cut pink construction paper out in shape of a pelican bill and tape to hat. Cut out eyes or buy those platic ones in the craft section of Wally World and glue on top of hat. Put her in a pink one piece w/footsies. Might be able to find this in the sleepwear section??? Then pin/sew/glue pink feathers to her bootie and maybe a few on her arms. Finally add shoulder pads, knee pads, helmet and a jersey number on the back. Might not want to give her a stick cause you'll end up carrying it the entire time.
Hmmmmmmmmmmmmmm.......scary that I came up with this in 30 seconds flat.
Good luck.
