Let's RePlay Ice Age 3 DoD Part 13 - A (Disappointing) Finale and Bonus

I really don't like this final boss, at least compared to the rest of game, especially the plant boss. Buck uses the Mushroom Weapon of Death to dislodge rocks to.. fall?... onto Rudy while Momma fights him proper. Afterwards, I look at the unlockables you get from crystals.
