Buying Melting Ice Cream from Paulie
Melting Ice Cream is a variant of ice cream in Epic Mickey 2: The Power of Two. It can be purchased for 50 E-tickets before fixing Paulie's air conditioning.
Just like ice cream, it can be sold to Laralee for the One Toon's Trash quest, but for a much higher price. Under it says "Melting ice cream is surprisingly hard to get." It would be recommended to get it while you can for the E-tickets and for the One Toon's Trash quest.
