A children's play toy includes an openable replica, a play compound within the replica, and one or more additional replicas nested within the openable replica. The additional replicas partially adhere to at least a portion of the play compound. For example, an oyster replica includes a play compound forming the mantle of the oyster and a second oyster which must be dug out of the mantle with a shovel or sword replica. The second oyster can have collectable pearl(s) contained therein. The pearls can then be assembled onto a customizable necklace and/or bracelet. The play compound which makes up the mantle can be independently played with. Children can use the toy to play with other children and to engage social media. The toy can be heat sealed to prevent the play compound from substantially moving or deteriorating before use.
