That's Toad. He doesn't have a partner. It could be Toadette because they have been partners since Mario Kart Double Dash, including Mario Party 7. To me, Toad/Donkey Kong, Toad/Rosalina or Toad/Kamek doesn't make ANY sense, but Toad/Toadette will be the perfect fit.MechaWave said:Because they are incredibly minor characters that haven't appeared in any major Mario games for a long time.
And this only further disproves the partner system exists. Toad and Koopa don't even make sense (Koopa/Shy Guy, however, does). Either way, someone doesn't have a partner/significant other.
Secondly, Koopa's and Toad's partner would need to be unlocked and I think the 2 hidden characters are Toadette and Shy Guy.
