Tập 15: Star Saber cử Machtackle điều tra một hố sụt ở Canada do Decepticon gây ra

15

A large sinkhole opens up in Canada, and Star Saber sends Machtackle to investigate. Guided by a local farmer, he examines the hole and splits into Mach and Tackle, who determine the cause to be the cutoff of local underground water. It turns out to be a Decepticon plot involving a disguised factory, and the other Autobots are quickly called in to aid the beleaguered pair. Tackle tries serving as the upper body in combination with Mach but fairs poorly, though his tactics enable the Autobots to drive off the Decepticons. The sinkhole soon becomes a lake, and Mach and Tackle celebrate their partnership. (Source: Wikipedia)
