This party was for my daughers second birthday.  For the invitations I found blank cards at Micheal's Dollar bins with a rubber ducky on the front.  On the inside I printed 'Splish! Splash!  It's Kailey's second birthday bash!' 'Waddle on over on May 20th, to Kailey's tub (address) We will have a splashin' good time 2-4pm, give us a quack at (number)' For the decorations I went all out.  I found majority of my stuff at the dollar store. I bought dark blue table clothes and dark blue and yellow paltes, napkins, and plasticware.  On the tables I had the birthday cake in the center of the table, I got it from WalMart, it was blue with white icing bubles all over it.  I put the rubber ducky candles on it, but only lit two when we sung to her. On both sides I had small metal bathtubs with rubber duckies floating in them. On each side of the table I had two metal tins and the read 'Duck Feed'  one set had goldfish crackers, the other set had Chex Mix trail mix in them.  The other table had the cups, plates, napkins and plastic ware.  I also had a blow up rubber ducky tub, which was hers when she was small. I filled it with ice and put sodas in it.  Then all over the table I placed small blue rocks that looked like bubbles. The front porch had duck web prints leading up to the door, with a sign that said 'Duck Crossing'  When you came in the front door there was a huge faucet my husband made out of cardboard and covered with foil. The faucet had blue and white streamers and bubble wrap cut into strips coming out of it.  And there were bubbles all over the livingroom floor.  You had to walk under the streamers to come through the door, so it was as if you were walking into a big bathtub filled with bubbles. I took my curtaines down and hung shower curtains, with a towel flung over it, in their place. Outside I had bubble machine for the kids to run trough and a small kiddie pool filled with bubbles and all diffrent kinds of bubble wands I found at the dollar store.  For activities I had punch balloons for the kids to play with and we had a bubble gum blowing contest for the adults.  The prizes were foam ducky purses from Micheals filled with bubble gum. We also had a relay race, you ran to the first line and put on a ducky float, then the next line had goggles and then the last line had orange swim fins, and then you had to run back to the starting point.  It was hillarious.  We sang Happy Birthday and had cake and ice cream.    then we opened presents, and after that it was time for everyone to go. For the parting gifts I found the Peeps bird squeak toys on sale after Easter, and then a small bottle of bubbles.  For the boys they also had a yellow yoyo and a ducky noise maker.  For the girls they also had a ducky comb and a cute plastic jewlery set. For the unfants I gave them a mesh bag with a mommy duck and two babies. On the bags I put 'Than you for helping Kailey turn two!  Here is a special gift for you.  Hope you had a quakin' good time.'  The were a huge hit.  IT was a wonderful day I had had many many compliments on the decor and party theme.
