This MLP papercraft is the Party Cannon of Pinkie Pie. This paper toy is created by RocketmanTan. Pinkie Pie is first introduced as a talented party-thrower. She runs off to plan a party for Twilight Sparkle immediately after seeing her for the first time, and throws many more parties throughout the series; Her first party ever was thrown for her family, which is how she got her cutie mark according to her own telling in The Cutie Mark Chronicles. She throws Gilda a welcome party in Griffon the Brush Off and Gummy a birthday party in Party of One. In Sweet and Elite, she organizes a birthday party for Twilight on very short notice, putting up decorations in very little time with the help of a "party cannon".
