Baby shower invites

Hi, Maybe you ladies can help me. My cousin and I are planning a baby shower for another cousin of ours, we would like to get invites with a frog theme (strange I know but she LOVES frogs) something suitable for a shower but not to froggy or baby showerish.

I hope I am making sense. We have been looking all day but we really didnt find any thing.

Does anyone have any suggestions. We are very open to making them ourselves.

Thanks
