On my daughter's 4th birthday, she wanted to do a "Hamtaro" theme because she loves the show. I drew pictures of the "Ham-Hams" on the invitation, while my daughter glued felt sunflower seeds around the picture! :) It turned out very cute, and I wrote "My daughter, (name), would be more than happy to invite you to our \*clubhouse\* in honor of her 4th birthday, where you can become a \*Ham-ham\* too!" on the inside with an orange & blue pen (because Hamtaro's orange, and Bijou's ribbons are blue.) We decorated the whole downstairs with orange and blue balloons/streamers and had her Hamtaro stuffed animals hung from the ceiling! LOL! Outside, My cousin and I put a brown circle-shaped thing made out of wood in front of the door so the kids can crawl through...(Hamtaro crawls through a dirt-tunnel to get in his clubhouse.) We made the hole big enough for the adults to go through, without getting stuck. When the kids got there, we served out the snacks: Salted sunflower seeds without the shell, pink and blue cookies, (we called those cookies "Diamonds of Sugar" because that's the name of a Hamtaro episode.) Iced tea, V8 Splash, and peanut butter and jelly! FOR GAMES: We hid my daughter's Hamtaro dvd somewhere in the house, (downstairs) and the kids had to look for it! It's like that "HOT/COLD" game. The first three girls to find the hidden dvd each win a Hamtaro book that I bought at Barnes and Noble! We had cake with the "Ham-hams" on it, and it said "Little Hamsters, Big Adventures" in it with orange icing! The kids loved the cake!!! In the goodybags, I put in Hamtaro stickers, a small bag of shell-less sunflower seeds, and pins that I made that said "I'M AN OFFICIAL HAM-HAM!" The kids had a wonderful time!!!!!!!!!!
