Super Widget (SNES) Boss Run (no damage, no abilities) + Ending

Please read this before watching the video: the bosses (and all regular enemies as well) of this game cannot hurt you if you touch them while they're blinking (that is, just after you attack them). That's why I sometimes get through the enemies without taking damage. Here is an incomplete list of the bosses:

1) Ratchet 1
2) Octopus Monster 1
3) Dr. Dante
4) ???
5) ???
6) Ratchet 2
7) Mega Slank 1
8) Gyp 1
9) Master Sorcerer 1
10) Flim Flam McSham 1
11) Rock Monster 1
12) ???
13) Ratchet 3 & 4
14) Gyp 2 & Flim Flam McSham 2
15) ??? & Octopus Monster 2
16) Rock Monster 2 & Master Sorcerer 2
17) Mega Slank 2 & 3

If anybody knows the missing names or thinks I've made a mistake, please leave a comment. Enjoy!
