You've met a terrible fate, haven't you?

You've met a terrible fate, haven't you?

Eye glowing space cat devours the earth

I am become dog, the destroyer of worlds

Mushroom cloud looks like a dog's face

Girl sees mushroom; boy says its a dog.

No kids, that's no dog it's a mushroom

that's not a dog, that's a mushroom

Kid has trained one-up mushroom
