Undertale - not sure what meme this belongs to

Howdy! It’s me, BARNEY. BARNEY RUBBLE. I owe you a HUGE thanks. You really did a number on Fred. Without you, I NEVER could have gotten past him. But now, with YOUR help… He’s DEAD And I’VE got the fruity PEBBLES! Boy! I’ve been hungry for so long… It feels great to have PEBBLES inside me again. Mmmm, I can feel them in my stomach… Awww, you’re feeling left out, aren’t you? Well, that’s just perfect. After all, I only have six flavors. I still need Cocoa… Before I become GOD. And then, with my newfound breakfast… Dinosaurs. Cavemen. Everyone. I’ll show them all the REAL meaning of this cereal.

Feel the wrath of the GRANDEST OF DADS!
