Summer/Windy Wings are way smaller than pegasi. They're about the size of G1 baby ponies. And their wings do usually stay put, unless a mean kid ripped them off... Flutter wings almost always broke off though.
*pictures Broken/missing wings ponies* *cries*.. boy Hasbro sure had fun coming up with Pegasi variants. why couldn't they do that with the unicorns? the only variant I've see are the alicorn/winged unicorns.. hey, how bout a horned sea pony or mermaid pony
