In the script to the season one
He-Man episode
"Evil-Lyn's Plot" writer
Paul Dini describes the
Widgets in some depth in order to guide the character design artists. Interestingly some of the descriptions are very different to what we saw on screen.
Kando, the leader of the Widgets is described as having a "white beard", something that never materialized in his actual design;
Lara is described as a "spunky tom-boy", which is an accurate description as to how she turned out; and finally
Squinch is referred to as a "Gabby Hayes type" character, which is obviously why
John Erwin developed such an odd voice! I should also note that the below picture from the season two episode
"The Littlest Giant" is one of my favorite images of the Widgets; so much so that I actually managed to buy this cel a few years ago!
