Helping Hand Land is where Harriet Hippo lives.
In Harriet Hippo and the Mean Green, Matt and Digit went to Helping Hand Land to find the Healing Stone. When Harriet Hippo appeared, she begins to tell them to follow her to find the Healing Stone. When Helping Hand Land is affected with the Mean Green, Harriet Hippo turned mean and green so Matt and Digit ran away from her. In The Snelfu Snafu Part 2 however, it's seen briefly.
