I have had these pinstripe discos since 06’ looks like some are bouncy.!? is that a thing?

my glass is hazy and this is a quick phone photo. But i never really thought twice about these mushies...

Looks like it. I have similar mushrooms and other than a few small patterned warts, I've never had them do that in the 20 years I've had them.
