Abstract: A realistic hatching of a dinosaur occurs from an egg-like storage container. A transluscent egg sheel includes a series of crack lines, which forms weakened fault lines on the surface of the eggshell. A compressed sponge dinosaur is located within the eggshell. Opening at the ends and/or sides of the eggshell allow water to enter the shell when the egg is placed in hot water of a preferred temperature of 50.degree.-60.degree. C. The water entering the shell, after approximately 5 to 10 minutes, causes the compressed sponge dinosaur to expand and break through the eggshell at random points on the shell, preferably along the molded crack lines of lesser thickness than the remainder of the eggshell. The rupturing of the shell occurs at its weakest points, as affected by the depth of the preformed cracks in the shell as well as the portions of the shell which have dissolved due to the exposure to hot water.
