Planking Challenge is a chapter of Pretty Cure: Magic of the Rainbow.
Chiyu attempts to break the record for the longest plank.
Tropes:
- And Your Reward Is Edible: Homare and Iroha take Chiyu to get ice cream for breaking the record.
- Luminescent Blush: Chiyu goes red in the face while trying to hold the plank without collapsing.
- Toilet Humour: Homare quips that Chiyu is making the same face Hugtan makes before she needs a new diaper.
