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°:

x = 16, y = 15, rule = 23/3 2o14b$bo14b$bobo12b$2b2o3bo8b$5b2obo7b$5bobo8b$6b2o8b2$8b2o6b$8bobo5b$ 7bob2o5b$8bo3b2o2b$12bobob$14bob$14b2o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ HEIGHT 600 WIDTH 600 THUMBSIZE 3 ZOOM 30 ]]

Higher-period analogues

The pond reaction is period-agnostic, so it works at higher periods. Three examples are shown below.
