Ash is given free tickets by 2 'Strangers' and goes on a cruise thinking about all the pokemon he might find. He sees there's a bunch of free food, he imediatly stuffs his face and feeds his pokemon.
He stops when he overhears a battle between a Raticate and a Starmie. "Wanna battle me?" Ash says holding a pokeball "Sure" he sends Ratticate and Ash sends Butterfree "Psychic" Butterfree attacks with physcic energy "Hyper fang" Butterfree evaded swiftly "Sleep powder" Ratticate falls asleep leaving it open to attack. "Let's just call it a draw"
Ash comes back to eating and sees Misty "Hey!" Misty looks up at him "Oh. Hi Ash!" The guy comes and says "I say I'm a big fan of your Butterfree. Wanna trade?" Ash decides to ask someone more experienced "Should I Misty?" Misty takes a break from eating "Training with multiple trainers helps a pokemon become more experienced. And if you want it back you can always trade back. Why not trade?" Ash nods "Alright then. Let's do it!"
Shortly after trading team Rocket attacks. But they're useless. Getting destroyed but in the prosses the ship is destroyed. Ash already misses Butterfree and trades back. But he and Misty end up not getting off in time and the ship sinks.
