A c trailer of infinitely extensible size and period, formed from two tippy trailers consuming an anchor track left by a puffer. The same reaction with only one tippy trailer is called a half anchor eater or anchor nibbler. The following is referred to as a six-slot anchor eater and is extended by inserting four more pairs of dots into the anchor track before the tippy trailer. Any spaceship formed from a flotilla of puffers and an anchor eater is called an anchor eater ship. The smallest currently known consists of two 3-2 dot puffers and a 3-3 sun puffer, as shown below. Compare anchor biter.
