Rich chocolatey weirdness

However tongue-in-cheek this ad might be, there's still something disconcerting about the way the candy bar turns into a lady with a baby-like speech impediment who seems to exist solely to stroke the hero's ego before he hungrily devours her. What's going on here? We saw it three times yesterday, and remained baffled each time. Why does she call him "panda bear"? Why does he act so creepy? (Also, for those who smell Milky Way payola: This panda bear doesn't like Milky Ways. The fluffy filling has a nasty texture.)
