Digging enemies tend to surprise me whenever I play with sound off (having my headphones next to me lets me hear most sound effects anyway, but not the digging noise). I'd like to suggest giving them some kind of visual effect, such as a small dirt spray when they're inside blocks. Hunter potions exist, but you're not going to have enough of them for whenever you're underground, and especially not as a new character which is when you're the most vulnerable to worm enemies. This would also double as an accessibility feature, for cases where "just always wear your headphones" isn't applicable.
