I need help remembering this game's title

I remember seeing this game being played in grammar school, so it was probably between 2005-2008 when I last saw it. All I remember was that it was sprite animated, and players would choose from a list of sprite animals to sit on for the game. The actual game itself consisted of players sitting on their animal on top of a pillar (or tower of some sort) and would take turns firing spells at each other in order to take down opponent's hp and eventually knock them off their tower. These towers were very narrow, with just enough room for players to fit on them. I'm not sure if the game was multiplayer or not, but 2+ players (or cpu's) were needed for a game. I saw it played on pc.

My apologies on this,because this is gonna be the last one-day account I could deal with.

It's not allowed to post something game-related in off-topic. here's the correct place to do so.
