HELP! I've planned a pool party for my kids but the weather is not cooperating!? - pool party name suggestion

I had a pool party planned on the occasion of the anniversary of my son for weeks, but the weather was terrible. We feel the full effect of "June Gloom" ... cold and overcast. I have about 20-25 children are sunny here for a pool party, but rather the cold /. Please give me some suggestions what I can do. Each alternative .... Please give some examples, if possible. Children between the ages of 7-11 years. The game is expected to be at home. I can not call to cancel because they have all the phone numbers of parents. Thank you in advance.
