Becquerel

Bec is, presumably, the/a pet of gardenGnostic. Like most things related to GG, very little is currently known about him.

Bec can talk or supposedly communicate very well with GG. When a meteroite landed near GG's house, Bec didn't want GG to go near it, thinking it was dangerous.

Dave describes Bec as a "fucking devilbeast" that should be "[taken] out behind the woodshed [where GG should] blow it's head off." gardenGnostic says she couldn't accomplish such a task if she tried; either she can't handle a gun or Bec is too strong to have it's head blown off. Speculation leans towards the latter, as GG says that feeding Bec is "always a bit of an undertaking" which seems to imply that Bec is large and/or powerful.
