It all started in a city in the park there was two guys (blue jay and a raccoon) named Mordecai and rigby was sitting up the chairs for the kids party

Mordecai: 36, 37, 38 38? Rigby?! Where's the next chairs?
Rigby: it ran out
Mordecai: we supposed to get to the 50!
Rigby: so it's Benson's problem
Mordecai: no rigby, it's our problem
Just then a vortex appeared as Mordecai
Mordecai: uh, rigby? Am I dreaming? Or a portal came out of nowhere
Rigby: I dunno, let's go inside it
Then Mordecai interrupted him
Mordecai: no rigby, rigby no! Benson will disappointed if we don't set up the chair as we're disappeared in another dimension
Then rigby ignored him as he entered the portal
Mordecai: rigby!
Then he entered the portal after him as they yelled inside it and then a light shined caused Mordecai and rigby covered their eyes as they're headed to another dimension
