The mole was introduced in Diamond Caves 2 and not Rocks'n'Diamonds (unless DC2 inherited it from RnD... ) so most of the mole tiles should be moved to the DC2 section. The only one that's actually new to RnD is the mole with the random start direction.
Mole is in the "RND" dropdown when it should be in the "DC2" dropdown
