The centaur and the horse don't look anything close to Pokémon.
Also, what happens in the animation after you put the Balls on that platform that comes out oft he floor? Also, why are there only three slots? Your animation doesn't make any sense.
The horses I know don't look like pokemon, because they aren't. When I made the tittle, I thought I had more animations, but I couldn't find them.
So the one animation I have is my first version of the animation.
The Platform where the ball goes, is how the pokeball is transferred into the PC to get healed.
In the later version of the animation, the first floor has two of those platforms, one for healing the pokemon, and one at the bottom of the stairs to take your pokemon, as (with my animation) you couldn't have pokemon on the second and third floor.
The first floor also had a total make over, the stairs were moved the walls were changed, the floor was changed.
The second floor, was a complete change from the normal second floors, the floor was actually twice as long, as it was a entrance hall for a "Hotel".
At the risk of boring you, I'll stop there.
Also, what are you talking about, "three slots"?
