The vibrating of the bumps all over its body causes earthquake-like tremors. Seismitoad and Croagunk are similar species.

Trivia
Even though Seismitoad and its pre-evolved form are normally immune to Electric-type moves (the type to which the Lightning type corresponds to) in the games, this card has a weakness to Lightning-type attacks. It might be because Tympole has a Lightning weakness, and Tympole is normally weak to Electric, which is the type Lightning corresponds to.
