The new toy set "Make Your Mark Collection" features five brushable 3-inch ponies: Sunny Starscout, Misty, Jazz Hooves, Pipp Petals and Queen Haven. It appears to be so new that it isn't listed anywhere online yet.
This was found today in a Toys "R" Us in Vancouver, Canada, by jorj/benjamin_li, who shared these six photos in the G5 MLP Discord server and gave me permission to reuse the photos with credit.
According to jorj, Misty's mane is "super soft and fine", unlike the others' manes.
The product cost 36.99 Canadian dollars, although this is probably more expensive than the MSRP/US price will be.
