Pippi chose an Oshawott when offered a Pokémon by Professor Laventon, and in her first trial she caught a Bidoof, a Starly, and a Shinx. After that she caught a Drifloon, then the alpha Kricketune, then finally a Pichu(!), and after calming Kleavor's frenzy she can now call upon Wyrdeer to ride.

Pippi's team now:
♂ Dewott lv20 (Kenki)
♀ Staravia lv18 (Muku)
♂ Luxio lv18 (Tora)
♀ Drifloon lv18 (Fuwa)
♂ Alpha Kricketune lv19 (Kohro)
♀ Pichu lv8 (Puchi)

Nao has a Mime Jr. and a Snorunt hanging around her house, but it's unclear if she's actually caught them or not. She definitely doesn't battle with them, though! A Bidoof will also occasionally show up to gnaw on her house; it's unclear if it's the same one every time but Nao insists that she is.

Nao's "team," for lack of a better word:
♀ Mime Jr. lv5 (Junior)
♂ Snorunt lv38 (Runt)
♀ Bidoof lv5 (Gal)
