We Love Katamari REROLL+ Royal Reverie

If you are wondering who Dr Katamari is, it's the cat with the weird face. Talk to it to play the two levels needed
The Doc wants friends, so the first time playing the level will involve rolling up lots of animals (friends).
Talk to the cat again later and play it again, this time rolling up about 100 friends in the shortest amount of time. There's plenty in the level so it is not a 100% thing like some levels. Once you beat both versions of the level, this should unlock upon returning to the menu area

Dr. Katamari appeared for me around Chapter 6/7. He is the cat like creature found on the bottom of the screen found by the Cowbear Farmer, Substitute Teacher and Cleanly Mom.

They have 2 tasks for you:
Task 1: Roll up Friends. You have 8 mins to roll up as many animal friends as possible.
I hit 157 animal friends (52%) with a total size of 6m 59cm which cleared the stage. I’m sure the amount isn’t a necessity for this stage but 150 should be a safe bet if you’re playing and learning.
Edit: Played the level again for cousins cleanup and 130 is a confirmed fail. 150 is your mark.

Task 2: Hurry, Your Firends. This task you need to collect 100 animal friends and there is no time limit. This is a very easy task so have fun!

Happy rolling!
