A milkshake created by Ralph 'The Rocket' Meckler. It is very similar to a Cream of Crankshaft except using mint chocolate chip in place of the rocky road ice cream and keeping the vanilla. M&Ms are also added to represent stars.
Ed: Hey Nelson, you thirtsy? Want a Cream of Crankshaft?
Nelson: I'd rather have another type of milkshake instead. But I'm not sure what kind.
Ralph M: (excited) I got one for you, Nelson. How about a 'Rocketshake'?
Nelson: Wow, Mr. Meckler! What's in that?
Ralph M: Well, it's almost like Grandpa Ed's Cream of Crankshaft, but you use mint chocolate chip instead of rocky road ice cream, there's M&Ms in it. I'll whip you one up real quick.
(Ralph M makes the milkshake)
Ralph D: (sweating and panting) What in the world is that? I've never seen a milkshake like that.
Ralph M: It's a Rocketshake. You'll love it.
Nelson: Whoah, this is awesome!! It's a real blast!
Ralph M and Ralph D: They don't call it a Rocketshake for nothing, boy!!
Ed: Ten stars!
