In November, The Powerpuff Girls and Japan's top fictional idol group crossed over to celebrate the 15th anniversary of the Powerpuff Girls ' Japanese television debut.

The Parco Museum in Sapporo is hosting the " Love Live! ~μ's meet Powerpuff Girls" exhibition starting on January 22 and is switching to a winter theme. The exhibit is taking cues from the idol group's popular single "Snow Halation" with new artwork.

Customers that visit the event and spend at least 3,000 yen (US$25.50) will get a postcard with the new artwork. The museum is also hosting a picture opportunity spot with a large version of the new image for visitors and T-shirts.
