Leading a Stray! - S12.E5

A Wailord blockage has trapped the boats in Canalave's harbor, and that means Dawn can't take a ferry to her next Contest. There's nothing to do but sit down for lunch, but a wild Luxio and its Pokémon accomplices steal the food! Pikachu and Piplup give chase, but run straight into Team Rocket. As always, Team Rocket tries to grab Pikachu, but Ash catches up with them and escapes into the sewer with his buddy. Piplup uses Whirlpool to toss Team Rocket, and now it's up to Ash to find his way back to his friends. As he wanders the sewers, he comes across the Luxio and its pals. They stole the food to feed a stranded Wailmer that somehow ended up in the sewer!
