When my igglybuff gets upset with me or another Pokémon she huffs and floats to the ceiling and puts herself in time out… why does she do this? Is she just an oddball?

Not at all, anonymous! Members of the jigglypuff line often inflate themselves when they’re upset. Igglybuff just happen to be light enough to lift themselves off the ground, although lighter jigglypuff can as well. So long as she’s indoors and away from ceiling fans, uncovered vents, or fireplaces with uncapped chimneys, she should fine. Just wait an hour or so for her to calm down and deflate on her own and catch her in a bug catching net if she wanders too far.
