A Mega-Tank rolls through the landscape as lasers bounce off its sides. As it rolls, it opens, charging its laser to cut through the heads of the trio of Tarantulas shooting at it. After the three of them are killed, three pieces of gray rock slam into the ground, right where the Tarantulas had died. The Mega-Tank, thinking it had won, stopped as it felt another laser hit its back. There stood three more Tarantulas, except each one was now a skeleton of its former self. The gray rock that had landed were Graveyards.
[the introduction of my own creation, Graveyards. Each gray stone is a gravestone with the monster's name and a picture of which monster was killed. The monsters it brings back can be skeletal or mummified versions of the monster that it had been]
