Depicted here is Samuel Adams, the billionaire-playboy-philanthropist and hugboxer extraordinaire, with four of the fluffies he owns. (Samuel Adams is a humanized Shining Armor, and a huge hugboxer) Each fluffy is based off a different hugboxer/neutralboxer from the history of the fluffy pony fandom.
 
The orange fluffy with a dark mane is Maurice, who is based off Waggytail ’s fluffies, specifically this image: >>2561857  
The white fluffy with a blonde mane is Prince, who is based off Carpdime ’s fluffies. >>2562229  
The red fluffy on the floor cleaning herself is Velvet, a Yehdoo fluffy.  
The blue fluffy on the floor is Rexxie, a Marcusmaximus fluffy who enjoys video games (both pc >>100188 and console >>336792 ) as well as dungeons & dragons. >>80733
 
All of these characters were introduced in Chapter 1 of the Sam Adams Guide. This image was used as the cover image of the Index of the first volume of the Guide.
