I got Bitil when I was 8. He had no mask. Basically my Bitil had the stupidest face ever. That's about the sobbiest story I can think of.
Other not really sob stories include:
-Breaking 1/3 of my red axle collection in half by accident
-Getting a Stars foot permanently stuck to a technic piece I intended to use
-Accidentally snapping a metru head's neck to bits
-Losing my zamor spheres. I have recovered one.
-Scratching some wood off the living room floor using Lewa's sword... somehow
