Here, the issues we face are twofold. First, we know not where our captors are headquartered. Second, a dinosaur would not fit well into the elevator. So our primary operation, instead of an attack, would be to carve a staircase into the tree with laserbeams. This then allows us the mobility we need to use our [the writing gets a little wibbly. She's laughing here.] sharks effectively. From there on we identify, locate, isolate, and remove those who we must to achieve our goal. I am assuming for the purpose of this exercise that our goal is freedom.

Elsewhere, the only proper use for dinosaur-riding laser sharks would be to overthrow and conquer the entire world.
