They are called puss caterpillar, fire caterpillar, woolly slug, or opossum bug.
I mention a website in the video, Tyrant Farms, https://www.tyrantfarms.com. They have a lot of great foraging and farming information and great mushroom information. Apparently I was wrong about who the tyrant is. It is the wife, not the son. The son is adorable. Thanks to him I was leary of strange caterpillars. So happy I didn't touch it
When it comes to this fuzzy caterpillar, you can look, but you sure don't want to touch.
Poisonous caterpillars, known as puss caterpillars, are once again popping up in Florida, and officials are warning residents not to be fooled by the creature's soft and furry appearance.
It's the most venomous caterpillar in the U.S. and even a simple brush with the insect can cause "excruciating pain," according to National Geographic. The caterpillars' fur hides toxic spines that stick to your skin.
