I've never really loved this set, TBH. Even as a kid I found Shoreline's symbols extremely unattractive, and my opinion of her hasn't really improved with age. Beachball's symbols never looked like balls to me, as a kid they looked more like planets. The other ponies in the set have grown on me in recent years though.

Have her. I quite like her colouring, even if her symbol is a bit forgettable.
 

I have a rare MOC Alternate Birthflower Daffodil/March on the horizontal Scandinavian card. The pony is still mint, however she has discoloured to yellow/brown on the display side, probably from being displayed in direct sunlight by a previous owner. I could decard her and treat the damaged vinyl and restore her to a crisp white pony, but she is more valuable as one of the few remaining examples of this line of pony in its original packaging. So she'll stay yellowed and discoloured, but it's more important to preserve her intact.

I is for Ice Crystal.

Lockdown gave me the opportunity to start working on my pony room, which has been a delightful diversion during such a stressful time. I'm a nurse so I'm still working as much as I ever did, but aside from going to work I've been housebound for months. Ponies have been a welcome distraction from the stress of work and the frightening state of the world. I've been adding to my collection quite a bit during this pandemic, I'm really grateful for social media's pony groups and eBay. When everything is going to hell in a handbasket, I can still rely on ponies to help make me feel better.

I have him. He's so cute, I love his symbol. I wish more ponies had been made this colour!

Six months ago I paid £235 GBP (approx $290 USD) for my Paradise Estate. Mine had no discolored plastic and the box was in good condition though, so I was willing to pay a little more because it was pristine.

I do love Mimic. Not a fan of the pose, but her striking colours make up for it. I'm lucky enough to have her. Am with you in the wish that they'd made more green ponies.
