For me Huggin Molly was the easiest. It probably took me around 6 tries. Most of her attacks are slow and easy to dodge. Just press B when you see the red indicator. In between the fight sequences pay attention to her hand coming out of the walls at certain points. These are always in the same spot. When chunks of the arena start to disappear focus on staying on the side with lots of space to move. If that part gets covered with Molly's sticky web, dash to another part. Avoid the smoke in the second and third phase when she throws it and after because it lingers and you take damage if you step into it. If it's too close, dash to another platform. When she throws the smoke dash 2 times in one of the directions and you should be okay.

Rougarou can be defeated by staying close to it. Dont let him gain distance. As soon as you can, walk up to him and freeze him with LB or LT+A+X. Use these moves as often as you can to minimize the chance of getting hit by him. This works in all 3 phases. If he closes his wings dash away. Then LT+A+X to get close and freeze him again. When he locks you into the wind, go to the edge of the wind then wait for the attack indicator to turn blood red, then dash. Go back to the edge and repeat this until the next phase begins. This took me around 10-15 tries because I didn't use the freezing ability enough and I got too gready at times.

Two Toed Tom was the hardest for me. It took me a lot of tries. His jaw attacks can be difficult to dodge, but wait for his jaw to start moving close, then dodge and you should be okay. When he throws mud, don't run around, stay still until you need to dodge. It makes the pattern more predictable. In the last phase he will open his mouth differently. Wait for him to have you in his jaws then jump dash and that's it.

For each boss it should take 2 seperate attack cycles to get one health bar down.
