Martin becomes distracted by zebras
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Martin initially creates a messy stack of beer mats on the table but then, for some reason, decides to start building on the back of the adult-size zebra rocking horse he had ridden into the room at the start of the task. He then brings in a smaller version of the zebra and also creates a stack of beer mats on the back of that one. For building in the wrong place, he is disqualified.
