The Frozen Party was a party in Club Penguin that began on August 21 and ended on September 3, 2014. It was first 'confirmed' by Spike Hike in a Spike Saturday meetup as a joke, but was later stated to be official.
In issue 458 of the Club Penguin Times, there was a new flash, mentioning a heat wave hitting the island. In issue 459, there was a report that Gary the Gadget Guy originally predicted warm weather, and there were plans for summer-themed activities. However, the weather report later showed a mix of hot and cold temperatures, prompting Aunt Arctic to invite "friends from far away" who would love a hot and cold themed party.

Spike Hike once tweeted that a Frozen Takeover could be made if there enough requests for it. Shortly before the party was announced, he stated that it was the most asked-for party.
In an interview, Polo Field said that the team has "something planned" in response to a question asking for confirmation of Spike Hike's confirmation of the party. But he could not say if the team was going to go through with it.
There was a Frozen DVD package including a free 7 day Membership code and a code to unlock the Snowflake Costume found in Australia Target stores. 
Polo Field stated that the first hint about August would come in the Best Day Ever music video. As promised, Olaf, the snowman from the movie, was spotted in puffle form in a crowd in the video.
It was the third sponsored party in 2014, and the tenth sponsored party overall.
The island was decorated like the fictional, Norwegian kingdom of Arendelle from the film. The Town, Plaza, and Dock was the kingdom castle and village area. The Forest has Wandering Oaken's Trading Post and Sauna. The Beach has the Valley of the Troll Rocks. Finally, the Cove and Snow Forts are based on Olaf's fantasy in the song In Summer from the film.
This was the first full party to be also held in the app.
