Great Start to our 4th Annual Event:

Posted January 5th, 2015

Thank you for the early registrations, donations, and offers to volunteer.

We are a small organization of volunteers and our success is reflective of the assistance we get from our community. Your efforts promoting the event and our upcoming auctions can be very impactful. As we did last year, we will have both an online auction (eBay) that is available to everyone, and a silent auction at the event.

For those of you interested; here’s a list of the various ways you may choose to support or organization:

  • Donate Auction Baskets:
  • Many of our fantastic auction baskets are donated by wonderful people like you! People find it fun and rewarding to build and donate a basket to our auction; popular themes are; Date Night, Movie Night, Sports Equipment, or some people even donate a set of their season tickets to a pro sports team.
  • Promote the Event:
  • There are many way to promote our event:
    • Sharing with others via email or social media
    • Sharing our posts from our public Facebook page each week:
    • Going to our Facebook page and using the Invite feature to invite your friends to like our page! (Left hand side of the page – click the “Invite” button next to each friend’s name).
    • Download and post our Flyer at your place of employment and other locations; church, schools, coffee shops, etc.
    • Distribute flyers; Peter and Christine can provide with you 10, 30, 80, whatever you think you can distribute. Just email us;
  • Share our Etsy Store:
  • Provide items for the Auctions: Perhaps you, your employer, or someone you know has a product or services they can provide? You can download our Donation Letter to provide to any businesses you frequent.
  • Sponsor the Event: We still have sponsorship opportunities open to help support our expenses. Our sponsorships range from $500 to $5000. Sponsors are acknowledged on our website and on signage at the event. You can download our Sponsorship Prospectus and visit our Donate page for more information.

Later in February our website will announce online auction details and have the waiver form available for download. This waiver form must be completed by all attendees. It helps speed up entrance to the water park by having them completed in advance. If you have any comments, questions, or ideas, please contact us at

Thank you for your support, Peter and Christine

Our Mission

Helping hospitalized children feel "over the moon" with essential childhood activities.

Mary "Moon" Jacqueline O'Keefe died at the age of 3 on July 30th, 2009 after a yearlong battle with neuroblastoma, a cancer that is most common in infancy. Mary loved the attention and activities Child Family Life Services provided her at the University of Minnesota Children’s Hospital, this allowed her to be distracted during painful treatments and to be engaged in learning activities while in the hospital.

Please visit Our Foundation to learn more about Mary and her parents' goals with our new foundation.
