Petunia Paleo is joining an expedition to look for some exquisite fossils. She and some diggers have found good one, but it's protected by some smelly deep mud..Petunia's proving the not even some deep, sticky, sinky, and stinky mud will dissuade nor prevent her from her archaeological work…

She must be aware of where it's safe to cross, because of the little amount of bubbling in the mud (She'd probably sink even deeper if there was more bubbling.) and the mud smells so bad that the other archaeologists in the expedition backed off, but not the aspiring Petunia Paleo.
