Transfering the grog from one cup to another

[⚜️ 卂乙乙卂尺卂尺]

I am at the point where I have to bring the grog to Otis to free him so he can join me to go save the mayor. The problem is that the cup melts and I don't know how to transfer the grog from one melting cup to a new cup. How exactly do I do that? Could someone please explain it to me as I have tried many times using both boards (CTRL) and (ALT), but can't figure out how to transfer the liquid. I would greatly appreciate any help. Thank you very much.
