There are a few scenes of mild threat in which the tiny snail characters are placed in danger. A couple of the scenes involve crows, who are seen swooping down from the sky to pluck up snails. There are some quite intense moments on the race-track, when the tiny snail speeds between the wheels of the racing cars, narrowly avoiding being squashed. The scenes of mild threat are short and we are never in any doubt that the snail hero will escape and triumph.
