Have you tested your water? Goldfish rarely jump out of the pond, but when they do it is often a water quality issue. Shedding slime coat can also indicate something wrong with the water. Any chance anything toxic has gotten into your pond?
It didn't jump out of the pond, it jumped out of quarantine shortly after I put it in, while I was waiting to see what people had to say here. My guess is that it was nervous or scared from being taken out of the pond and put into something so much smaller.
