The TzRek-Jad apparently has a chew toy named Mr. Squeekles. Conversations with the TzRek-Jad seem to indicate that this pet should grow to be a TzTok-Jad and artwork (see below) seems to confirm this. If a player examines another player's TzRek-Jad, it will display the owner's total number of TzTok-Jad kills in the chatbox.
