The definition of 'Freakshakes' I found says that 'they are Bigger & Better Milkshakes' - & I agree with that. Because they are like Milkshakes + Sweet Bonus at the top. 

And this 'Sweet Bonus' can be: Sweets, A Piece of Cake, a whole Donut, Marshmallows, Whipped Cream, Cotton Candy - So All the Sweet, Yummy & Colorful Things that make it even 'better'. I mean Look & Taste Better than a 'Regular Milkshake' 😊👍

*This book was inspired by the Milkshakes I saw in 'Crazy Party Forest' videos - because I'm 100% sure that All My Fellow Trolls would like Freakshakes you're going to See in This Book as well !  ^_^ 👌
