Does he spin the tentacles very fast to change into the Sharktopucopter to generate the Sharktopusnadio?
Not yet. But my guess is that's cued up for version 3.
Sharktopus already vanquished the Pteracuda threat and it was a flier.
But that does open up food for thought - Perhaps the third Sharktopus movie will coincide with Sharknado 3. If that happens there really wouldn't be any reason to watch tv anymore. Nothing could top that.
Well except for Sharktopus & Sharknado 4 of course.
