Ferb Fletcher (2nd Dimension)

Ferb is a character in the Phineas and Ferb: Across the Second Dimension movie

History
Most probably born within Doofenshrimtz reign, he has never heard of summer vacation and only knows of Doofenshrimtz way of life.

When he was young, his and Phineas pet, Perry, disappeared, never to be heard of again.

Ferb is a kid who likes to keep quiet and out of trouble, not going outdoors because of patrolling Normbots outside as well as his mother's instruction to never speak to neighbours, as they could be dangerous. He normally hangs around with his stepbrother.
