QUALITY - 80s American Animation Was The Best

Let's see:
One table briefly disappears, then reappears
A soldier disappears just after another one appears next to him
All the tables vanish completely
Hole in wall extends to floor, defying perspective
Hole in wall disappears after T-rex walks through
Triceratops phases through the unbroken wall

Yep, it's QUALITY.

And the carnivorous T. rex eats a salad.
