I was planning on releasing a video of the full boss fights after finishing the game but then I realized Hilda's fight took 35 minutes...

The Root Pack: 0:00
Goopy Le Grande: 4:55
Cagney Carnation: 10:27
Hilda Berg: 32:00
Ribby and Croaks: 1:10:48

Also, I totally didn't keep the last clip going for a couple seconds too long
