(leader sings one line and everyone else sings it back)

Flea.

Flea fly.

Flea fly mosquito.

Oh, no no no more mosquitoes.

Itchy itchy, scratchy scratchy, oh, I got one down my backy.

Beat that big bad bug with the bug spray.

SSSSSSsssssssssss!

Here's a second version of the song, sent to me by Leslie Collins. Thanks!

(Actions: the song is sung sitting crosslegged and alternate clapping once then slapping knees once to make the beat)
