dig a big hole vs. create a secret passageway
Dig a big hole then put a cozy little grate over the hole and maybe hang some vine from it. Make it all nice-like
if you think about it, what is a secret passage if not a big hole rotated 90°? and isn't a big hole just a secret passage that takes you into the earth? not only can the two be combined, they are, in fact, one and the same
When me and my friend were kids he would come and have a sleepover and then at like 2am we would get the sudden urge to dig a hole so we would dig a massive hole in the backyard (so glad we didn’t ever hit a gas line wowee, I know better now) but anyway the hole would take us all night to dig and it would be gigantic and then we would find random things in my moms shed like old toys and stuff and bury them in the hole, one time we buried a plastic skull I hope that confuses a future archaeologist
