Pets can be made permanently rideable if they are given a Ride-A-Pet Potion. This Ride-A-Pet Potion is available for 150 robux; it can be bought through the 'Shop' menu or inside the Potion Shop. You must buy a potion for every single pet that you want to make permanently rideable.
If a parent is riding a pet, the pet will grow bigger to accommodate the parent's size. If a baby is riding the pet, the pet will stay at its normal size.

Pets can be made permanently flyable (allowing the player to sit on the pet and fly it) if they are given Fly-A-Pet Potion. This Potion is available for 295 robux; it can be bought through the 'Shop' menu or inside the Potion Shop. You must buy a potion for every single pet that you want to make permanently flyable; both Fly and Ride potions can be used on the same pet to make the pet flyable and rideable.
If a pet is in flying mode, it will grow white wings with a pink trail, unless its original state had wings, which it will use as its "flying" wings. The Arctic Reindeer, Pet Rock, and Reindeer pets do not need wings to fly and as such, don't gain any.
