Though there’s less ‘Crusading’, and more ‘Mischief Making’
 
“I have a plan to cause some real fun in this town. You gents in?” - Robin
 
They all finally have names!  
Ridley (left) is the son of Scootaloo and Gabby  
Robin Rich-Apple (centre) is the son of Applebloom and Diamond Tiara. (though he prefers to be called by his nickname; Puck)  
And Clay (right) is the son of Spike and Sweetie Belle
 
In my world, it’s impossible for hybrids to get Cutiemarks, so Ridds and Clay are gonna be blank flanks forever, that doesn’t stop them from having fun though. Our boy Puck is much more interested in causing trouble than looking for his cutiemark, which suits them just fine.
 
In the middle of colouring this picture, I decided to record it and made a speed paint. So yeah, you can watch that too.

Edit: Clay was a little difficult to see on DA so I added a black border.
