Forum - Sgt. Frog Water Inflation

I recall seeing a moment in the series where one of the members of the Sgt. Frog team, Tamama, had a hose in their mouth as they chugged down a good amount of water for a task they have to do. The last scene had them on the floor with the hose still connected to their mouth with a big water bloated body.

Any clue when this happened?
