[He has some vague, dreamlike memories of ice skating from his time as a kid a few weeks ago, so when Goku sees the lake all set up for it he decides to give it a go. He rents some skates from the Usyagi and sets out onto the lake!
Starting out he's a bit wobbly on his feet and might get caught using his staff to push himself along. But, after ten minutes or so, he finds his balance and starts skating laps around the lake comfortably. After a while that gets boring and he picks up the pace, zipping around the lake at dangerous speeds and swapping between skating forwards and backwards as he tries to amuse himself.
Eventually even that gets boring though and he flops over onto the snow at the edge of the lake. He'll sit there for a while with a hot chocolate in his hands, watching everyone having fun with a bittersweet smile on his face.]
