Phineas and Ferb Fanon
Isabella's Cousin

Popina

Popina Sharina is Isabella's cousin and she has a crush on Ferb. It is unknown how Ferb feels about her. She freaks out when she sees Phineas' inventions and tells Isabella that her freinds are crazy. She only appeared in one episode, named, Isabella's Cousin, and never came back. She has green skin because I felt like it!
