I found some interesting content on Metal Heroes wiki
https://metalheroes.fandom.com/wiki/Siba-tiba
Zaido: Pulis Pangkalawakan is a tokusatsu series from Philippines. Siba-tiba a monster from this series has a power to enlarge stomach of victims. I also found some clips of Zaido but I don't know about episode with inflation scenes.
