basketball mascot like me. I'm a mascot
for the Temple University team. I entertain
the fans at matches and other events. I
wear a red owl costume and do silly
things I slide across the court throw
sweets to the fans and celebrate when my
team scores. I have to be creative to think
of different ideas to entertain the fans.

speak a word. I love the work and it's well-
paid but it's tiring. Luckily, I only work
part time!
