Help!?!?

Okay, so the creative "party planner" has hit a dry spell! Yes, it's true. Walker's birthday is two weeks from yesterday, and I have no idea what I'm going to do for it. I know this might not seem like that big of a deal for some, but for me it's HUGE! The past three party ideas (Walker's two and Will's) just miraculously came to me with no effort on my part. Those of you who attended these know how big of a deal my boys' birthday parties are to me and how I tend to go all out. I just can't bear the thought of them looking back at pictures from their birthday parties and not seeing decorations, friends, cake, etc. But that's just it--the past parties have just been a big deal to me, the boys could careless, and quite frankly were not that aware of what was really going on. But I think the importance and fun of the big number 3 has finally started to sink in for Walker. For the past month he has been chattering non-stop about his "birday party coming down". So this is the first one he actually cares about so I want to make it special for him. But I have no inspiration and I feel like my creativity is hitting a dry spell! Oh, he is asking for a turtle cake, so any ideas spinning from a turtle cake? Maybe I could make it like a "reptile" party or something, like with lizards, snakes, turtles and such? I don't know...... Ideas for fun locations?........Your brainstorming is needed...... HELP!
