Isabella Garcia-Shapiro is the across-the-street neighbor and good friend of Phineas and Ferb. Isabella has a crush on Phineas; however, she doesn't tell him. She's the leader of Fireside Girls Troop 46231 and often volunteers to help in Big Ideas, usually with her troop being involved.
Scooby Doo and Shaggy sent across the multiverse to solve mysteries with some iconic new friends. Unlike the New Scooby Movies or Scooby-Doo and Guess Who, each episode will see them team up with the cast of a different cartoon series (appearing in their animation style) and catching a new version of a classic monster.
