Level 103 is somewhat like a chamber where the fruits are locked (preventing spoilers here). Players with Unstable Explosives, like Zax and JoeKickass, can make a bomb throw them over the ceiling so that they can get further in the caverns, instead of rescuing everyone.
However, we're not missing much. Levels 104 and 105 are nothing, and 106 only has a platform that prevents you from going further, thus needing to Ctrl+Shift+K or wait for the fireball to kill Igor. It's only for the top level.
Before The Great Update players could get 'till level 116 without the Unstable Explosives, and these bonus levels were actually puzzles instead of nothingness.
