The caterpillar of that species looks like a tiny toupee or mustache, but is one of the most venomous caterpillars in existence. They’re native to where I live and we call them “asps”.

With my daughter she was absolutely terrified of falling into the big potty. We got to her use the training potty fairly easy by just making it available, but couldn’t get her to transition to the big potty. We got it to work by taking the small lid off the training potty and putting it over the seat on the big potty and she then felt safe enough to start using it. Overall it was a bit of a fight, but she’s been using it for over a year now, and all has been good since.
