I think that you can change your nitendo watch so winter will come back...

If you change the time, you have to wait 24 hours untill it takes effect (I've tried it)

Answer 1

Twist Mountain(reach different caves, and find different things, like trainers and items) and Iccirus City(double grass and an item)

Hope I helped:)

The most important item is tm substitute in twist mountain

Answer 2

"Some piles of snow allow you to access areas you can't during the other seasons. This occurs in Route 8, Icirrus City, Moor of Icirrus, Twist Mountain and Dragonspiral Tower."
