That's not a bounce in terms of if it's the colorful WWC Bounce you see for retarded prices, and if he's implying it is then you're buying from a guy who's knowingly and actively trying to scam you. It is technically a "bounce" in the way the term gets thrown around to describe any Rhodactis with bubbles on it, but to be honest that microscopic mushroom is never going to be worth triple digits. Just be aware they paid around $3-5 for it and if you think it's worth what they're charging then it's your money.
On a side note the multicolor bounce mushrooms that are like $6k are about to dive-bomb in price. A few different suppliers across the country just imported around 60 of them total and a lot more are on the way, my guess is in around 6 months you'll find frags for well under $100 once the right people get their hands on them.
There are some badass bubble "bounce" mushrooms that aren't the multicolor though, I have two of these and they're pretty awesome
