Cuts to cutaway gag:
Peter (dressed like Red): Welp, I swam here, without the help of one of my Pokémon. Sweet, a truck. I'm gonna drive it hehehehehehehe.
Peter: *Drives the truck a bit*
Peter: *gets out of the truck and sees Mew*
Peter: Oh sweet, a new Pokémon, gotta show Professor Oak!
cuts to Pallet Town
Peter: First, I need to make a stop.
Peter enters Red's house, goes up to his room and says "See, I own all 151 Pokémon now, you silent little bastard!"
And then Peter goes to see Oak.
