The tub-with-tail eater (or eater 5), commonly abbreviated to TWIT, is an eater composed of a block and a tub with tail. It is capable of eating gliders from two perpendicular directions. It is generally used to absorb gliders in situations where the standard eater is insufficient, particularly because of its edge-eating ability. The eater 5 can be constantly renewed and hassled with an eater 1, giving the eater/block frob or the eater/long-hook-with-tail frob.

Variants using different still lifes are possible. For instance, the block can be replaced with a more complicated catalyst, or extra catalysts can be added to perturb the block. Eaters created in this way form a significant proportion of Dean Hickerson's eater collection. A commonly applicable variant uses a long hook with tail rather than a block to catalyze the reaction, which can be used to compress Herschel loops to periods of 57, 58, 59, and 60.
