I can't judge the plushies, but the Ponies are lovely!!! I have all four Celestials, some individuals in boxes, & some white Ponies I bought to customise & support BF.
I also now have the Rescue At Midnight Castle set & they're cute!!! Just like McD's Ponies with their moulded manes, brushable tails, & small size. I love them & am more excited about the blind box Ponies now too!!!
On the McD's comparison, it's legit, especially if you think about McD's G3 Ponies. They were cute, nicely made, & a worthy addition to a collection!!! They're among my faves to Customise too!!!
You'll love yours when you get them!!! Don't forget to add pics!!!
