You can move animals from side to side. You have to collect full horizontal lines to make them disappear. Some animals are frozen and must be released twice, some are locked in cages and cannot be moved. Use bonuses when necessary. The first two bonuses destroy animals located in a vertical and horizontal row. The third destroys animals within a radius of three tiles and the last animals of the same color.
Slide Pet blocks and create full lines. Move Pet blocks to empty positions and create full lines to remove lines.
