North West's third birthday party arrived with a splash! (I had to.)

The 3-year-old partied with family and friends at a mermaid-themed birthday party that makes all other children's birthday parties look like a floating pile of sea trash. The sea-based shindig took place and Kim and Kanye's Bel Air manse, but on Thursday, they also took the whole crew to Disneyland to experience the princess magic IRL. 

Here are a bunch of snaps from the day, in which all of the Kardashian children look like they have no problem walking and are super happy!

And of course, those who want to play at home can drop some very real cash to attend a very fake birthday party:
