Evil Inc After Dark #31, Page 2 (Patreon)

As I said in the most recent AMA column...

...Octo Lad — was created on the fly. I realized I needed an extra person in the locker room as I was pencilling the scene. And since all of the other characters were humanoid, I figured it would be nice to add a non-humanoid mutant to the mix. So I free-associated my way to Octo Lad.

As I was inking him, I realized what Multiplex points out in Panel Two. I had only given Octo Lad seven visible tentacles. Remembering the great fun I had the last time I drew a tentacled creature*, I decided that the eighth tentacle should be... well, extra special.

It turns out that Octo Lad is a grower, no a show-er. Most of his sexual equipment is kept internal until it's ready to use.

*It was "Space Pirates."  The rather "handsy" alien first appeared here.
