Watch toddler Ruby go crazy when she opens her Christmas present.

RUBY Ryan must have been really, really good this year.

Not only did she get what she wanted for Christmas, but opening it appears to have given her unparalleled joy.

In a video captured by dad Chen Ryan, Ruby can be heard screaming in elation after discovering that her longed-for Anna and Elsa Frozen dolls have arrived.

The Sydney toddler becomes so excited when sees what lies beneath the wrapping paper that she just loses her cool completely, shouting: “Oh yeah! Oh yeah! Oh yeah!” on repeat.

Mum Kylie Ryan told news.com.au Ruby, who is three-and-a-half years old, had wanted the dolls all year.

“I knew she’d lose it, she was so excited about Christmas,” Mrs Ryan said.

Mr Ryan posted the video on Facebook this morning, with the caption “When Santa gets it right”.

Like pretty much every little girl on the planet, Ruby became enamoured with the princess sisters after watching in the blockbuster Disney animated film Frozen.

And she certainly isn’t able to “let it go” after getting her hands on the toys after so much anticipation, with the thrill of it all lifting her from her feet as she utters a seemingly endless high-pitched scream.

Frozen has so captured the hearts of children around the world that Time published an article explaining the psychology of its incredible appeal, as did CNN.

The prevailing view is that toddlers relate to the central character’s struggle to regulate her emotions, along with the movie’s focus on the bond of love and loyalty between two sisters.

The Oscar winning film, released in 2013, was Apple’s most downloaded movie last year and is the highest-grossing animated film of all time.
