Go Away White-Marked Tussock Moth Caterpillar

I love being outside. Love sitting in the grass and feeling the blades tickle my ankles. Ah, that’s a pretty active tickle. That’s not grass, something’s crawling on me. Yikes! What is that thing!? Yellow, fuzzy thing with a red head and… is that a stinger? What are those white balls on its back? Are those eggs? Is this thing poisonous? Get off me scary caterpillar! Go away you white-marked tussock moth caterpillar!
