This is a comparison of Ghost Bloo from the FHFIF episode “Bloooo” and Ghost Filly Apple Bloom from the Milkshake! Mix episode “Apple Bloooom”. I think they’re very similar. I just watched them both and they’re both amazing!
 
Also, in the FHFIF episode “Bloooo”, Eduardo, Coco and Wilt didn’t know that it was just poor Blooregard with a really nasty cold, and in the Milkshake! Mix episode “Apple Bloooom”, Foxy the Pirate Fox (from Movieunleashers), Jeffy and Zalgo Pagie didn’t know that it was just poor Apple Bloom-regarde with a really nasty cold.
