Cyndaquil's from Nintendo's Pokemon, Bo-BoBo's from Toei's BoBoBo-Bo Bo-BoBo, Spyro's from Activision's Reignited Trilogy and this screenshot's taken from Valve's Garry's Mod. It is done through  David-967's choice as part of the celebration of late Valentines and early Easter Days.

Spyro accidentally flew to the wall when he was actually aiming at the wide open door. Now that BoBoBo and the brave little Cyndaquil are working hard to try to get the dragon dude out of it.
