Though Magisprout are typically found in weed-choked ponds, heavy rainfall and flooding can displace the Pokémon into streams. Their weak muscles force them to move with the current, and they become easy prey for predators.

A Magisprout's thin and flexible body lets it bend and sway to avoid any attack, however strong it may be. Its swimming muscles are weak, so it is easily washed away by currents.
