Original Description:
 
Based on a fan fiction I’m writing on fimfiction!
 
It’s about three ponies (and one creature) being transported to an unknown world and having to find a way home. This is their reactions to being transported to where in the world they were transported too! They were separated so they are really far apart.
 
Izzy is yet to realise she’s alone.
 
Obviously I’m yet to draw the third pony but, can you guess who it’ll be?
 
Hints:  
1: It’s not a main character  
2: It’s an earth pony
