Mulling over words again

In cricket, a mullygrubber (or simply grubber) is a delivery that, whether intentionally or accidentally, travels more along the ground than through the air. It's fair to say they are despised by batsmen.

"Mulligrubs" was an Aussie TV show for little kids that I recall my youngest sisters watching, and which centred on a disturbing disembodied face. With a disturbing high-pitched voice to boot!

I tried to brainstorm a third similar word. Rule Of Three and all that. Best I could do was mull - a nickname for marijuana where I grew up. Now, I'm picturing a stoner chuckling at "Mulligrubs".
