Generation 3.5 ponies were the unpopular transitional generation between G3 and G4, and only lasted from 2009 to 2010. Although they are technically a part of G3, the majority of collectors consider them 'G3.5' because they look completely different from the rest of the G3 line that was familiar to collectors. While lots of collectors loved the adorable Newborn Cuties (like little Toola-Roola in the banner above), the actual baby/adult G3.5 pony style was not very well-liked in the collecting community. I personally don't mind them, although out of all the generations, they are definitely my least favorite.
