Grookey and co. are musicians. Music = sound = Normal-type. Could also be part-Rock if it has a rock music genre theme. Rock is a big aspect of modern UK culture.
Fire/Fairy
Nothing fairy about this thing. At all. Fairy is reserved for wily, trickster Pokemon, cute/feminine Pokemon, or Pokemon that ooze beauty. None of those applies to Sorbunny. Could be part-Fightng due to how the Pokemon is associated with a contact sport (international football, like Passimian is American football). Could also be part-Electric if it generates its own energy (but that could just be a Fire-type trait, much like Victini gathering power).
Water/Poison
Chameleons are not poisonous. Just because Acid Armor (which this Pokemon isn't even confirmed to learn, btw, and level-up type movesets don't even matter in many cases for a certain Pokemon. Most likely going to be Water/Dragon since the lizard-like Pokemon disappearing into the water has strong ties to Nessie. Ghost makes no sense either since it's not based on an extinct animal species.
