Magnus, Spyro and Cynder are from Activision's Spyro, Zak and Wheezie are from Dragon Tales and this screenshot's taken from Valve's Garry's Mod. It is a gift for Twitter's CoolDewott.

Magnus just finished training his dragon friends on how to be like him, to be a mighty kind of a dragon as well as to be a chunky kind. He has indeed taught them well enough for him to be proud to see their bellies big enough to be weapons and shields against many bad guys.
