Three Best Foal Friends

Decided to draw a tribute to my favorite background colts and filly. I've loved Pipsqueak since episode 4 aired and who can't love Featherweight? And then Dinky, because she's obviously best filly.
I have this headcannon that they would be super friends when they get older. Especially Featherweight and Pip. I wouldn't even be surprised if they were brothers, honestly. Their color pallet is so similar.
Anyways I had to improvise on Dinky's cutie mark and Pip's is covered but is supposed to be a moon-shaped blade. I don't really know. :/
