Randolph the Rat's Adventure Lab Cache starts near here.

Randolph informs me that being a T5 Rat is not just doing the occasional tree climb, running an ultra Marathon, going out to shred the trail, or doing a Hoppit once a year, it requires training all year around.
Anyway, that is what he tells me when he nips off leaving me to write up his adventure caches.
So what the Adventure Lab Cache does is follow the Rat, and see what he really gets up to.

To find this mystery you need the five code words from the Adventure Lab.
Write them out, no spaces, all CAPS (if there are numbers, spell them out),
and add them to the checker below.

You can validate your puzzle solution with certitude.
Hopefully, it will then tell you where the Rat has hidden this cache.
That's all there is to it.
Good Luck.
