Fighting the Transformed Goo

A brown goo turned into a dinosaur. And now, there's a possibility of that dinosaur to use magic and destroy everything.

So, we can only fight by letting Celestine take care of the dinosaur's magic to not destroy the dungeon, while I will fight upfront.

And although I hate the Professor, I want to have faith in this modified room that it can endure the attack of the dinosaur.

The dinosaur the brown goo transformed to was called ankylosaurus. A dinosaur with spiked shell armor on its body, with a tail that seems powerful and a bulge at the tip. Like a bludgeon.

The swung of that tail was enough to destroy a cage made of glass. In fact, even a baby with a stone might be able to break that glass. Why is it a normal glass and not reinforced glass? Did they have enough faith in their ability to not make this goo to attack them?
