Odd shaped cavity cutout

[Patty Hann]

I'm looking for suggestions on how to cut out ("hog out"?) a roughly egg shaped cavity in a piece of maple 1.5(H) x 2.5 x 3.5".
The cavity is not symmetrical. The side thickness is not critical... it can be anywhere from 5/32" to 1/4" thick.

I've attached some pics of monkey pod dishes that have odd shaped cut outs, so you can see (in general) what I'm talking about.
I'm not doing anything with monkey pod (good lord, why would any one make monkey pod candy dishes...there are tons of them out there in every conceivable shape, and some shapes not so conceivable).

But I am making a wood art project and need to make a cutout. It's not so much the sides as the bottom that stumps me.
What tool(s) do I need and what kind of bits?

Any suggestions/advice/caveats would be greatly appreciated.

I do not have access to any CNC equipment so, please, no suggestions on how to do it that way.
