Equestria Daily reports that Build-A-Bear’s image archives now have product images for alicorn Twilight and Spike.
Twilight looks to be about the same size as Rainbow Dash and Pinkie Pie and can be expected to be a similar price. She has shiny wings and horn, much like the fabric used on Rainbow’s wings, along with Luna/Cadance-shaped wings like she has in the show.
The image of Spike is much smaller; he might be a “mini furry friend,” a smaller plush animal generally under $10. He could also be sized differently and be a full-sized plush like everyone else, which would lead him to not be in scale but be much more cuddleable.
BABW staff have reported that these would be the next toys, with these images confirming it. Release dates, prices, accessories and other info is currently unknown.
