I think many people remember the Japanese game series, Mr. Driller. There was an arcade machine and several console games, and they were pretty popular. The idea was to drill through coloured blocks, periodically refilling your air supply with oxygen tanks.
However, does anyone know what Mr. Driller says whenever he picks one up?
Here's my attempt:
He always says something like 「えき!」
Since "air" is 空{くう}気{き} and "oxygen" is 酸{さん}素{そ}, I tried searching for other things.
「てき!」made no sense, meaning "opponent" (敵), etc.
「へき!」means, among other things - "barrier" (壁).
Other games in the series have similarly unintelligible (to me) quotes upon picking up air tanks.
Here's a link to some gameplay, and the first two oxygen tanks are picked up at 0:15 and 0:25: https://www.youtube.com/watch?v=KeSEoA1JKJA
