ELI5: How is it possible to have different sea levels if all the oceans are connected?

For example how can a sea level rise in one ocean and not the other?

Watch a big ass twerk in slow motion.  That's how ocean levels on the Earth work.  A change in one area doesn't immediately effect 100 miles away, there's ripples.  You have tidal forces from the Moon, weather, ocean currents, and land masses all effecting sea levels in their own way.
