A gentle story about a little snail called Henry who was born without slime and therefore will never be like everyone else.

When Henry finds out he is missing the most important element for snails—their slime—giving up is not an option for him. He tries to find ways to be able to climb things just as the other snails do. He struggles a bit before he finds the right solution, but in the end, he becomes the inspiration for his fellow snails and makes a lot of friends along the way, teaching us that far from being an obstacle, a difference may prove to be the key that opens new horizons.

Using a simple story and a sympathetic hero the kids learn social-emotional skills and are better prepared to cope with everyday life situations.
