Biting off more than they can chew (or eater-bound pond) is a period-3 oscillator found by Peter Raynham in July 1972. Its alternate name of "eater-bound pond" comes from the fact that in generation 1, the object between the two eater 1s is a predecessor of the pond.
The oscillator can be extended by placing more copies of the middle object, rotating each new one by 180 degrees.
