The Shy Guy, Luma, Hungry Luma, and Octoomba all have proper entries for the Just Enough Resources (JER) Mod, except for the Maw-Ray and Boom Boom, which both do have drops. Boom Boom registers in the JER Menu, but his drop doesn't appear (The 1 Power Star Drop Entry), and the Maw-Ray doesn't register at all in the JER Menu, despite dropping 1-3 Coins on death.

Here's some screenshots of the ones that do work properly:

Here's Boom Boom registering in JER, but not his Power Star drop:
