I know this is is kinda random and just decorative, but I think it would be pretty cool if this was added in the next update.
Make it so that when the player surfs and has a pokemon that can learn surf and could be realistically surfed on* in the first party slot, said pokemon would be surfed on instead of the Instant Lapras.
*Larger water-type pokemon, like Blastoise and Gyarados, could be surfed on, but not smaller water-type pokemon that can't normally carry a person, like Polywag or Quilfish, or certain non-water-type pokemon, like Rhydon, Tyranitar or Aggron.
