Have you ever taken a casual glance at your African violet, and suddenly noticed it was no longer violet--more like a dull grey-brown? Paging Dr. Frog!

This amphibian physician monitors your soil conductivity level and alerts you with an intermittent croak when things have gone awry. For your green pal to know when to croak, you need to preset the device to measure the ground and tell you when the conductivity level falls below a certain point. It also includes an integrated light sensor and is powered by two G10 batteries.

If you're worried about Dr. Frog waking you up at night with his periodic croaks, not a problem: He has an internal timer that tells him to sleep at night. Dr. Frog goes for £7.99, roughly $13.51.
