I got tons of submissions, so thank you to everyone that participated! It was a lot of fun narrowing down the names, and it was harder than I thought. In the end, I decided to choose not one, but two names, since I created another character similar to Mister X. The names I chose were mostly based on the character fit. I also tried to stay away from names that were attached to other well-known books and/or movies, or anything having to do with religion or cultural folklore as not to offend anyone.
With that said, the names of the icky little creatures are Keme and Scrimshuk. Thank you to Catalina Ballard and my sister Lyn for coming up with the names (and I swear I did not choose Scrimshuk because my sister suggested it).
I plan on having a character naming contest for my next book as well. And no, this sequel will not end on a cliffhanger :-)
