Where to find it

• Scripted encounter (Lv. 10): Pal Park — standing Pokémon.

  After the Cianwood Gym story opens the Resort Zone, enter Pal Park’s Fixed Catch mode for $10,000 with room for six more Pokémon in the PC. This standing Pokémon appears on Thursday or Saturday. Bring your own Poké Balls.

• Gift (Lv. 25): Ecruteak City — Shellos boy’s house.

  Tell the Ecruteak boy “Then give it to me”, with a free party slot. Choosing “Don’t give up on it” permanently loses the gift. Quest guide.

Pal Park: The wild table changes with the day of the week (by the DS clock). You get in through the Catching Show's Fixed Catch mode at the Pal Park reception ($10,000; bring your own Poké Balls). Sunday's table is the same as Cerulean Cave's, probably by mistake in the hack, so it also has Surf and fishing slots: the park has a pond and a stretch of sea.

See the quest guide: Resort Zone: the Pal Park's Fixed Catch mode (wild Pokémon by weekday).

Evolves into Gastrodon at Lv 30.
