Sparkling spots
Sparkling spots are small gold stars that can be found along walls and rocks in the game. They can be blown up with bombs (or anything that inflicts explosive damage, including enemies' attacks,) to reveal secret rooms and crawl spaces.

Crawl spaces

There is only one hidden crawl space under a rock per floor and it cannot spawn under rocks containing gold or in rocks located in secret rooms. Very rarely, another crawl space may spawn per floor in Othermine. Right now the only known version of it contains the Pilfer Market which has 3 connected Pilfer Shops. Crawl spaces are marked on the mini-map.
