What is this tube! Please help :(

Hello all, I was in the process of changing my spark plug and I noticed this tube coming out of the bottom of the right side of the intake box. (Pic below) It was hidden really well. So well that I didn’t notice it even when I stripped the bike down to change the plastics to black last year. Can someone tell me what it is for and why there is a blue liquid inside? My coolant is green colored. I don’t drive in deep water. Deepest water I’ve been in barely touched the foot board. Thanks in advance 🙂
