Mind Candy and toy manufacturer Vivid have teamed up to raise money for the U.K.’s Great Ormond Street Hospital’s Children’s Kidney Centre with the launch of a special Moshi Monsters charity tin.

Released Saturday, Mind Candy and Vivid hope to raise £100,000 to help children with kidney problems. The limited edition Goshi Moshi tin contains an exclusive metallic blue Moshling collection and is being sold across the U.K. at The Entertainer, Argos, Toys ‘R’ Us, Smyths, Amazon, WHSmith and the Moshi Monsters e-store.

The partnership was launched with a special visit from Mr Moshi and the Monsters to the hospital last week. Katsuma (one of the most popular Moshi Monsters) took a break from life in Monstro City to meet patients and families at the hospital and was joined by Moshi Monsters creator, Michael Acton Smith.

“We are excited to launch the new Goshi Moshi tin and hope to help raise lots of funds for the centre,” says Smith. “We left the visit feeling really inspired by the patients, their families and the dedication and skill of the staff. The hospital means so much to so many people, and we’re very proud to be supporting the charity.”
