Balloon Boo appears as a boss in Super Mario MHL.
Balloon Boos reappear as enemies only again in New Super Mario Bros. VR, where they are quite rare, but appear in the first ghost house of World 7 and then in the castle, where a giant blue Balloon Boo is revealed, called Bumper Boo.
Balloon Boos appear here as enemies found in Ghost Houses and, occasionally, in fortresses. Like in their very first appearance, these enemies puff up when being faced by the player and deflate to chase him/her
