- The episode title is a pun on the phrase "Coo Coo Ca Choo".
- This episode introduces Zoey's Blue Aqua weapon, the Strawberry Scepter.
- Episode 26 is the last Mew Mew Power episode made by 4Kids Entertainment. The rights to dub the original anime series, Tokyo Mew Mew, were lost and 4Kids was not able to finish the second half of the series, leaving Episode 26 as the series finale of Mew Mew Power. They may not have finished it anyways, considering the content of the last two or three episodes.
