Kaiketsu Zozori

'Kaiketsu Zozori' is a series of Japanese children's books created by Yutaka Hara in 1987 and continue to this day. It has been adapted into multiple anime series in addition to movies and manga. The main character is the wanted criminal fox Zorori and his small boar apprentices Ishishi and Noshishi.

S2E1: The Ghost Forest's Electric Eel
Ishishi and Noshishi accidentally over-inflate Zorori's scuba suit.

S2E19: The Great Zorori Circus
Zorori wears a clown costume in his act with his apprentices, which inflates enormously before exploding.

S3E5: The Great Help Yulia Plan
Zorori's suit turns out to have been an invention used to keep him out of the way by the episode's villain, a balloon suit. Upon activation, it swells up and causes Zorori to float in the air. He's able to use his flatulence to overfill it until it creates a hole, making him fly around as the gas is released until it gets further punctured, leading it to deflate.
