Authors Note: this is just an idea for a possible pet/assistant for J-Rod, and it's in the form of one of the more cowardly Beastlings.

Creature Designs: Klik the Blinder
As one of the few docile Beastlings in existence, Klik is both a pet and an assistant for J-Rod, and amazingly, the creature seems happier in the safety of Area 51 than he does in the actual field. But that doesn't go to say that Klik won't get aggressive, but only in the case of protecting his owner, and like Brittany's Medic Stitch, Klik is just a durable as Anthrax and cannot be killed (whether this is natural or genetically added to keep the team from having to hunt down more Blinders is unknown).
An interesting trait to this Blinder is that his exoskeleton is not black, but rather a deep red color more similar to Vesuvius, and he can communicate with others in an expression J-Rod called "vocalised Morse code" which consists of the critter clicking his teeth together in Morse code and having someone translate, though he can also communicate by means of a telepathic link with J-Rod.
Like other Blinders, Klik has a ball on the end of his tail, which has a glowing bulb inside it, but amazingly, this creature has learned how to dim it down to something more like a flashlight. Like J-Rod, Klik likes tacos and hotdogs, but loves to eat practically any type of food, though he can't stand peanut butter, mainly because it's so sticky to him.
There you go, just an idea I had, I have no clue as to whether or not this guy will appear in the story, but still, let me know that you think in the comments below…not literally, click the review button if you're new to this site.
