Nik Kershaw " The Riddle"

First day of new challenge! how many days before I really get obscure?
Another hot day at the nursery searching for caterpillars in the poly tunnel! in the end just had to get under the hosepipe, could have entered a wet T shirt competition (and shorts) it didn't half feel good! ( Pinched the riddle from work)

Tomorrows ditty is Pink- blow me one last X ???????
