Tito and Bibmo are partners ,Tito is blind and unable to see this gives him many disadvantages and many advantages . He can't get his food so Bimbo has to get it for him. Although Tito can sense some things that many others can't, those are what his advantages are.
Mt. Vesuvius is building up smoke and about to erupt.
The people in Pompeii think that the smoke is normal so they just carry on with their day.
Tito has no sense of direction and faints, so Bimbo bites him to get Tito to regain consciousness.
Tito gets lifted up into a boat without Bimbo.
Tito escapes Pompeii safely ,but Bimbo dies on the island trying to get Tito food.
