They spy on the Fixies and threaten their privacy. Who are these strange robots-crabots, what do they need and who is standing behind them? It turns out that Eugenius has an old enemy, and the Professor is challenged to a duel in order to settle old scores! New friends, Mega and Alt, will come to the aid of our Fixies, and
everyone will get into an incredible whirlpool of adventures!
