A pet anteater featured on a show on animal planet called "Pet star". His claim to fame is that he attempted to climb a ladder to reach the baby food at the top of it. Unfortunately his time in the spot light was cut short, when he made it to the top of the ladder, passing up the food. When I think of someone who has failed to complete a task I would call them an antony the anteater.
"You are an antony the anteater!"
(You are a loser!)
antony the anteater=failure
"You won't ride that roller coaster your an antony the anteater!"
antony the anteater=coward
