Original Description:
 
The six friends go to a rather unexpected sleepover, but they find it very relaxing and unwind from the long days doing adult stuff. Being a foal really is more simple. The ponies all doing their own thing really, besides three of them playing with the toy train model and train track set.
 
(From left to right) Beau Style (blonde earth stallion right behind the model toy train track and The Flying Scotsman model engine), Tilly, and Dropkick (The one laying down on his side and watching the steam model engine run on the track). Delta (Reading a book while sitting on a giant teddy bear), Shatter (Doing a jigsaw puzzle piece and showing obvious signs of her mouth fixation as evident with the pacifier), and Sirius (in the start of doing a drawing with some crayons).
