I finished a limerick, but was not happy with the versions that included enjambment, and so I bailed. Precarious Travel does address both the form and the prompt (imperfect).
and now I believe I have achieved at least one enjambment:
“Precarious Flight” (Take 2)
When Chester went down in the flight
balloon, there was scant time to relight
the gas nozzle there
that heated the air,
keeping Chester and basket upright.
