I've got a new story for you and like my heroes phineas and ferb I'm gonna do it in one day. The story takes place the Saturday 2 weeks after the end of the series finale last day of summer.

(in the second dimension prison, alternate dimension doofenshmirtz is raging)

'I was so close to taking over the 1st dimension but then that stupid boy Phineas Flynn had to go and ruin everything!'

(suddenly a portal opens and out comes a slimy green tentacle and the body it belongs to )

the creature speaks 'I know how you feel! I almost took over the seven seas but then that little brat melody ruined my scheme!'

Doof is intrigued by her explanation.

'a squid whose plan was ruined at the last second by a girl named melody eh? you must be morgana correct?'

the voice speaks 'that is correct.'

doof decides 'I'll make you a deal, morgana. help me get revenge on a young boy by the name of phineas Flynn and I'll help you get revenge on melody in exchange '

Morgana agrees.

Doof tells her 'I have a plan! at the moment nothing is more important to the phineas Flynn kid than his darling girlfriend this young girl named Isabella Garcia Shapiro. So I'll restrain him and you kill the girl in front of him' they agree to the plan while laughing maniacally.

Will their team up plan work or will phineas and Isabella find a way out? find out shortly
