Tree trunk
From Tardis Wiki, the free Doctor Who reference
In Earth-33⅓, Zarbi had tree trunk-like legs.
The Seventh Doctor explained that Doctor Who fans had been living under the misapprehension that the mighty tree trunk-like legs of the Zarbi were one of the less imaginative creations of the costume department when in actual fact they were way ahead of everybody else in the workout and exercise age.
