The achievement is not currently implemented properly, so the description is inaccurate. I was able to get the achievement by spamming four snowballs at the same bell four times in a row. Not even intentionally, I just got bored and spammed snowballs at the bell and the achievement came out of nowhere. Not sure if this will be patched, but personally, I highly doubt it will.
I threw my snowballs at the G bell, which is directly above your head as you spawn.
Works as of 10/04/19, comment below with updates and dates if it does or does not work for you so I can know to edit or remove the solution.
