The new McDonaldland shake, depending on which size you order, runs between 510-900 calories. Here's what it tastes like.

Recently, Happy Meals included McDonald's-themed toys -- such as drink machines, fryers and trays with food on them -- delivered in mini-Happy Meal boxes. And the much-longed-for Snack Wraps finally returned after a viral fan campaign.

The "Mt. McDonaldland Shake" is inspired by the "vibrant blue 'lava' and pink clouds of Mt. McDonaldland," part of the McDonaldland fantasy world that entered pop culture in 1971. The shake is described as having "hints of berry flavor" and "colorful, cloud-like pink Dairy Whipped Topping made with real cream" on the McDonald's app.
