Just when I was about to complain that the lack of actual villains for the Rescue Bots to fight is making the their show seem like another "s#!t happens" series, with drama being dictated by whatever random accidents the plot requires...
Holy slag! That could mean it's an invasion from the Migo of Yuggoth, or Rios from Metroid, OR--dare I hope?--
Yes, YES, YESSSS!!! Before the debates about whether this cartoon has continuity with TF Prime are resolved, we get potential continuity with ROBOTECH! Ohhhhhh, the miracles of cross-promotion Carl Macek could work with HUB programming if he were still alive!
Then again, it could just as easily be an homage to 'Piranha 2', where they were crossbred with flying fish. Whatever. And it'd be cool if the kid kept one as a pet and named it Nautilator or Sea Clamp.
