What to do with a "sleeping" pacman?

[diabolique]

Hi people,

due to Eyespy's reccommendations in regards to substrate on my last post I elected to change my pacmans frog substrate to a mixture of soil (80%) and Exoterra's "Jungle Earth" (20%) which is soil and woodchips. After my frog figured out what had happened he went and buried himself in the substrate. That was in early September.

I haven't seen him since.

Once a week I gently disturb the earth over top of him just to check and see if he is alive, and when I do this he starts making loud "growling?" noises. So then I cover him back up and and he stops and then we go throught the same thing the following week.

The tank that he is in does have a water bowl which i am diligently cleaning and keeping fresh water in even though he hasn't been using it for over a month. It also has an undertank heater on one half of the tank, (which he is now nestled up close to).

I have been watering the substrate as well, not soaking it but moistening it. Is this the proper course of action? or should I let the substrate dry out? I do not know how to care for him during this period of time.

I think he has eaten like 4 earthworms in the last 2 months total. Before he went into his little "sleep" I was offering him food and he would not eat. And now obviously he is not eating either. Oh I guess I should probably mention that he is approximately 3 years old, and I am assuming a male otherwise he would be bigger.

Is this normal behavior? How do I take care of him at this point?

Thanks in advance for your responses
