The Moshi Monsters: Mash Up Party is the fifth series of Moshi Monsters: Mash Up cards. The theme of the series is party, hence the card design, name and packaging. This is the first Mash Up series to consist of mostly reused art and some Moshlings have been excluded in order to make room for new ones. (It is also the first series to exclude a card puzzle.)
The cards were released on August 28th, 2014, but some were given out to people in the queue to meet Mr. Moshi at the Moshlings Madness at Bluewater event. The event was held at Bluewater Shopping Center, Kent on August 2nd, 2014.
Giant cards (about half the size of a person) were seen during a Topps Festival. Known giant cards are Mr. Moshi and Squelch.
They are the second series of cards to cost £1, the first being Moshling Madness. Similarly to the third series of tattoos, the packaging is portrait. This is the first series to have the Mash and Mosh numbers ranging to 999 instead of 99.
