Flying creatures are enemies in Droplets.
This enemy appears to be a golden yellow cube-shaped creature with two wings, an angry expression, and a grey, frowning mouth.
They fly back and forth in certain patterns and are usually in vast numbers. If a rabbit touches one, they will be electrocuted and (afterwards) die. The creatures appear to resemble birds, and are introduced in level two.
Breaking laser beam
Breaking laser beams will kill a rabbit on contact. After a long period of time, the laser beam will temporarily shut off but will quickly turn back on. In some levels, the laser beam is activated by passing the two grey blocks.
Moving spike racks
Moving spike racks are encountered on only one level and have an ability to turn. Rabbits can only pass them when the racks are in a horizontal position.
