Never heard the shoots bit. Makes sense, but becomes cumbersome & lacks punch for mine.
He's a Wombat! ... "A Wombat?" .. Yeah,... "Eats Roots, & Leaves .."
Guffawing ensues ....
I had it on a t-shirt in 1971, and it was definitely eats roots shoots and leaves.
Yeah, it must be in both forms, or they just dropped the shoots bit for that added punch.
A google on Eats Roots, & Leaves is interesting, They are both out there, as are other versions, Wiki has an entry for Eats SHOOTS and Leaves, seems that started for Pandas ..
The Wommy with Shoots, and w/out are both prominent, weird I've never heard it, but I s'pose it comes down to locale
vv.... Only way I've seen it on a T ...
Hard to believe others haven't seen/heard it in it's contracted, and waaaay more eloquent form.
