1. Put the Sine and Bullet behaviors on the beecalmask object instead of the bee. (You should always move the base, not the top. As an analogy: you want to pull on the wagon, not the rider.)
2. Put the beecalmask object into a container with the bee. (IMPORTANT - this helps pick the right bee when the mask is picked)
3. Destroy bee and mask on startup.
Event 3 is "On collision between beecalmask and ground."
Also, use the layer name instead of calling for the number... layer numbering seems to be wonky right now.
By the way, your game is looking pretty slick
