From the ad, and I do realize it’s just an ad, it kind of looks like some movement or interaction of sorts could be involved in the mosasaur scene. Love to see the flipper patent utilized to knock our boat timed with the mosasaur knocking on the glass.
The first few bumps could use the same mechanism that the hadrosaur off course effect uses, timed with the banging on the glass. But then the last bump, as seen in the commercial, actually pushes you along. Could scare the crap out of people, and add something more to bring a screen effect into real life.
