Fluffy

Fluffy was the name of the cloud utilized by a Lakitu in the Nintendo Comics System issue "Cloud Burst".

Unlike most other Lakitu clouds, Fluffy displays some level of intelligence as he is shown to be capable of speaking. Fluffy is also much larger than a regular Lakitu cloud, having room on his body for two people and an extremely large amount of treasure.

In "Cloud Burst", Fluffy aids his boss, a kleptomaniacle Lakitu in stealing the treasures of both Bowser and Princess Toadstool. It is unknown what became of Fluffy at the end of "Cloud Burst" after Luigi pulled his escape hatch, dumping all of his and Lakitu's loot onto the ground below.
