A novel moisture detector for detecting moisture in potting media or soil for plants includes a body formed to represent a creature. Inside the body is a processor and a battery. One or more probes adapted to be inserted into soil extend from the body and send an electrical signal to the processor to indicate a level of moisture proximate to said probes. At least one eye of the creature carries a light emitting diodes (LED) that lights up when the probes are inserted into soil having insufficient moisture. Furthermore, when the user touches one of the eyes, the LED lights as long as the battery has sufficient power to operate the processor.
