When you beat the Game Boy version of Dr. Mario on level 20 at high speed, the final version of the underwater scene has the UFO trying to beam the 3 viruses up into it (like in the original NES version), but as the viruses are underwater here instead of up high on a tree, a big shark intervenes and eats the three viruses before they can get inside the UFO, thus causing the UFO to retreat in defeat. May I ask, wasn't there a version of the same ending without the shark intervening?
