“Here’s news, @nickjfrost and myself will be once again stepping into Shaun and Ed’s shoes for the #PhineasAndFerb Halloween special. W00t!!”
“Phineas and Ferb” is a Disney Channel animated comedy about two stepbrothers who find inventive things to do on each day of their summer vacation such as building a roller coaster out of materials you would find in your everyday home like Popsicle sticks, indoor plumbing, etc. Unbeknownst to them, their pet platypus, Perry, leads a double life as a secret agent.
