>>10741166My Skydive is still going strong even though he's over 20 years old (ignore the rubber band in the pic - that was there to hold him posed with his neck extended, a trick I use for a bunch of my other toys with similar gimmicks during photography). Like with every toy, minute differences in the actual plastic used, the environment, and how often the toy is handled all play into the tolerances.
Also, yeah, check on your Snarl - the original release is known for suffering from GPS and dissolving, which is why I specifically went for the Universe version of him, who supposedly doesn't suffer from the same issue.
