Ash's Palpitoad

Ash's Palpitoad was a Pokémon that made a debut in BW035. Ash found Palpitoad while trying to find some medicine for his Pokémon after Ash's Oshawott defeated the group of Tympole. Palpitoad attacked Ash and he used Oshawott to battle it after Oshawott finally opened his eyes while using Aqua Jet. He hit Palpitoad and knocked it out, and then he caught it. As Ash had a full party, Palpitoad's Poké Ball shrank and was disabled. He caught it the same time Cilan caught his Stunfisk.
