Coridden is an action RPG with shapeshifters in which you can ride your friends
The one great weapon in my arsenal as mercurial uncle and cousin to several infant humans is the timeless game of Horsey. You know - when you get down all fours and offer to give the kid a ride around the sitting room. It's murder on the old kneecaps, but as any shrewd parental tactician knows, Horsey is a game with a sting in its tail (making this a kind of scorpion Horsey, I guess). The horse in the game of Horsey is free to choose the direction of travel, even if it's somewhere the rider would rather not go. Towards the bath or dinner table, for instance. Towards the dentist, if needed.
