From source (5 June 2022):

After the magic restored, there are some damages in Maretime Bay that needed to be repaired. With her generous nature, Pipp had an amazing idea to host a charity concert to help funding the repair cost of Maretime Bay. To execute her idea, she had some help from her sister Zipp and her new friends: Sunny, Izzy, and Hitch altogether in their newly bonded friendship.

Pipp had to wait for her trousers to be done so she were able to rehearse. Seeing Pipp in her rehearse, Hitch decided to toy with her. And it worked just the way he anticipated. Poor Pipp was in panick despite using her trousers.
