[If a 7-foot-tall walking tree has escaped the forest, how startling is it when you're creeping along trying to find frogs, run into a faceful of flies, and then suddenly realize the shadow you mistook for a good ol' oak actually has hair and not leaves and is apparently an animal whisperer?

Well, first of all, Lenka's mouth doesn't drop open because there are flies everywhere and he already regrets everything. Second of all he does his best to scramble backwards out of the swarm, slips on a bit of pond bank and falls over.

The good news is: he didn't fall on one of the frogs. The bad news is: his mouth did fall open when he went down, and now he's definitely coughing and regretting everything because he never needed firsthand experience of these bugs or what they tasted like???]

I... don't think... the flies--

[He doesn't manage to finish that because he's still trying to cough up fly bits. Gross...]
