It was a hot summer afternoon at inkwell isle. You start feeling sweaty from all the hard work or you feel the heat that there's a little air conditioning inside the bakery. That's when chef saltbaker called you.

Chef saltbaker: I have found the new ingredients on making ice cream.
You: just ice and milk?
Chef saltbaker: not only those two, but also these other ingredients! What do you say?
You: let's make ice cream!

You and chef saltbaker made ice cream for about 1 hour.

At the time the bakery opens, the customers see the ice cream and start to get interested in them. They buy so much until they are cooled down from the heat in the summer.
