Sometimes, size DOES matter.
And the answer to why Lobo stays a frog is answered. It wasn’t originally scripted to be revealed, but hey, it was able to be worked into this page fairly well, plus I had space for more dialogue around the original punch line. ^_^

Comic Dialogue
(If you have Wii Gloves for you wee little fingers it’s also electronic Braille.)

The Witch Gazel: “Just calm down, toad. I was only having a little fun with you. You’ll have to absorb this brew for me to see what your spell status is…”
Helga: “If he was a half giant, why doesn’t he just make a new character instead of sticking with this one?”
Libby Belle: “That’s a good point… Lobo, why don’t you just make a new character?”
Lobo the Frog: “Sheesh, Any other character would have to be a starting race as this was the only hybrid choice I had and I’ve used up this option. Plus, there’s the giant strength, do you know how rare it is to successfully breed with a giant? There’s the whole size issue…”
Helga: “What did he say?”
Libby Belle: “He said he won’t make another character because he’s lazy.”
Lobo the Frog: “That’s not what I said!!”
The Witch Gazel: “Okay, the brew is complete. I’ve got good news and bad news…”
Lobo the Frog: “The ‘Good news’ better not have anything to do with a tasty frog stew”
The Witch Gazel: “Okay, I have bad news, and not as bad news…”
