These are all part of a Power Miners lego set. It's called a fire blaster. There's a rock monster, a power miner in a lava suit, and the fire blaster. As you see, the rock monster is trying to eat the crystal. You could do something funny with the rock monster. When he eats the crystal, you could shake him up, and the crystal rattles inside.
