A reusable, fluid-swellable absorbent composition is disclosed. The composition generally includes a superabsorbent polymer, a gum, a film-forming resin and gelatin. The composition may further include a colorant and/or reflective particles, and it is particularly well-suited for use with amusement devices, such as for use by children. The device includes at least one sample of the invented composition, preferably including colorant and/or glitter, a volume of water and a structure including a base and a closed perimeter extending outwardly from the base. The structure includes a plurality of discrete regions, and may collectively resemble an object, scene or other image. Then upon placement of a small quantity of the composition into a particular region and addition of water to the quantity, the composition swells, expands and generally conforms to the shape of the region.

1. An amusement device, comprising the combination of: a fluid-swellable composition including gelatin and a granar superabsorbent polymer; and a play structure having a base and a raised perimeter region extending away from the base, wherein the structure is configured to receive the material on the base within the perimeter region and further wherein adding a volume of water-based fluid causes the material to absorb the fluid and expand upwardly away from the base. 2. The device of claim 1, wherein the composition includes a colorant. 3. The device of claim 2, wherein the color of the colorant is not readily perceptable to a user until a fluid is added to the material. 4. The device of claim 1, wherein the composition includes glitter. 5. The device of claim 1, wherein the composition further includes a gum and a film-forming resin. 6. The device of claim 1, wherein the structure is shaped to include a plurality of regions having walls extending generally away from the base, each region having a perimeter defined at least in part by the walls and the perimeter region of the structure. 7. The device of claim 1, wherein the shape of the structure is selected from the group consisting of animals, fictional and nonfictional characters, storybook scenes, and landscapes. 8. The device of claim 1, wherein the structure includes a cover distal the base. 9. The device of claim 1, wherein the perimeter region of the structure is transparent. 10. A method of using an amusement device; providing a play structure having a base and a raised perimeter region extending away from the base, a fluid-swellable material including a superabosorbent polymer, and a volume of a water-based fluid; depositing a portion of the fluid-swellable material on the base of the structure within the perimeter region, and adding the volume of fluid to the material on the structure, thereby causing the fluid-swellable material to absorb the volume of fluid and expand within the structure and away from the base. 11. The method of claim 10, wherein the fluid-swellable material includes a colorant. 12. The method of claim 11, wherein the color of the colorant is not readily perceptable to a user until the fluid is added to the material. 13. The method of claim 10, wherein the fluid includes a colorant. 14. The method of claim 11, wherein the fluid-swellable composition includes reflective particles. 15. The method of claim 10, wherein the material includes a gum and a film-forming resin. 16. The method of claim 10, wherein the fluid is water. 17. The method of claim 10, wherein the structure is shaped to include a plurality of regions having walls extending generally away from the base, each region having a perimeter defined at least in part by the walls and the perimeter of the structure. 18. The method of claim 10, wherein the structure is formed of molded plastic. 19. The method of claim 10, wherein the shape of the structure is selected from the group consisting of animals, fictional and nonfictional characters, storybook scenes, and landscapes. 20. The method of claim 10, wherein the structure includes a cover distal the base. 21. The method of claim 10, wherein the perimeter region of the structure is transparent. 22. The method of claim 10, wherein the material has a particle size in the range of approximately 100 microns and approximately 300 microns in maximum diameter. 23. The method of claim 10, wherein the material has a pH in the range of approximately 7 to approximately 7.5.
