"Heather is Back Again!"

We start off watching Heather Blake, in a silver bikini top and silver boy-short bottoms walk through the mud. She gets stuck while mucking around on the bank of a deep mud hole. Eventually she gets into the deep and treacherous mud hole, up to her chin, where she rolls around and tries to wipe the sticky mud off her body, only to be re-submerged! She climbs out of the mud hole a couple times and then jumps back in, feet first.
We get a great view of Heather's amazing backside, at the end of this movie, getting into a smaller mud hole and climbing around on the grass mounds surrounding the hole. Heather doesn't go completely under the mud in this one, only up to her chin, despite a couple feet-first jumps into the mud hole!
