Transcript
This harmless creature does very little but sit in the long grass and feed. With blunt claws it tears at the grass to disturb gnats, then inhales them through its short trunk.
The fatsack is a living bag of weak digestive juices that slosh noisily when it moves. Gasses build up inside the creature and are released from its trunk with a sound like flatulence.
