Unpleasant Horse is a sidescrolling platfromer for iOS devices. It is made by Popcap.
The protagonist of the game is a black horse, which the user must direct across the level by having the horse bounce on clouds, and on the backs of white horses. This causes the white horses to fall onto meat grinders at the bottom of the level; if the user misdirects the black horse when trying to hit a cloud or a white horse, then the black horse itself falls onto the meat grinders.
The game is complete, and was believed to be rejected from the App Store for "mature content" on April 7, 2011 due to a miscommunication.
