One of These Things Doesn't Belong

Can you figure out which thing it is?

1. Green Grass
2. Tulips
3. Snow Covered Trampoline
4. Daffodils

If you guessed #3, you guessed correctly! What the heck is going on with the weather though?? It was downright cold last night and we woke up to snow this morning. It better freaking warm up soon or I'm going to go a little batty!
