To Cool Oneself
To Cool Off
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means cool (temperature-wise) and the verb vocab version is to cool oneself or to cool off. Whoo, that feels much cooler now.
すずむ
You use a special product in a can to cool off with. It's an experimental product that was made by the zoo you're at (because this zoo is really warm, and it's nice to cool down). You use it, and it burns your face off. So, you sue the zoo (すず) for the face burning.
