'''Tail''' (sometimes referred to as '''L''' or '''J''') is a [[Polyomino#Tetrominoes|tetromino]] and predecessor of the [[beehive]]. It can often be attached to [[still life]]s to create a larger still life (eg. [[tub with tail]], [[beehive with tail]]). Even more important are the ways in which it may be attached to a marginally stable object of any kind to obtain overall stability while suppresing (or possibly exploiting) its own spark. The simplest such example is [[eater 1]], in which a tail and a [[pre-block]] mutually stabilize one another. A tail can also stabilize one end of a [[fuse]] (e.g. as in eg. [[fuse with two tails]]).

Tail (sometimes referred to as L or J) is a tetromino and predecessor of the beehive. It can often be attached to still lifes to create a larger still life (eg. tub with tail, beehive with tail). Even more important are the ways in which it may be attached to a marginally stable object of any kind to obtain overall stability while suppresing (or possibly exploiting) its own spark. The simplest such example is eater 1, in which a tail and a pre-block mutually stabilize one another. A tail can also stabilize one end of a fuse (e.g. as in eg. fuse with two tails).
