[Dungeon][Minor Quest] Lizard hunting in the abandoned labratory

"Oh me, oh my, oh me, oh my" woefully cries the eccentrically dress man in jesters clothes. He introduces himself as Mister Mizo of Mizo's Magnificent Travelling Circus! He explains to you that he has travelled with his caravan to these wet lands to find and capture a species of rare creature known as "shocker lizards. And he was successful in his little safari until the largest one they caught, an alpha nicknamed Bruno managed to zap a trapper silly and escape with all his shocker lizard buddies into a long abandoned research laboratory of some crazy dead guy.

Normally, Mizo explains, he would just go down there and collect them again, but the blasted things have jump started the generator room, reactivating the lab's security systems! Mizo wants your party to travel down there with this shock proof cage, and he will pay you for each shocker lizard you bring back ALIVE. You may also keep anything you find in the lab.

The dungeon will be a series of puzzles, traps, and construct fights , with brief breaks to capture the lizards. Bruno is nested in the last room and should act as the "boss" of the dungeon as a solo encounter. The room Bruno is in houses a weird machine that doesn't seem to work anymore. It looks like two telephone boxes wired together that lead to a third. On the floor, inside the third is a gold ring. When the ring is worn the wearer is able to talk to the ring (an intelligent item) that explains this was his lab, one of his experiments went wrong, and he has been on the floor of this room for decades. The voice says he will make himself useful if you take him with you. The ring gives +5 to knowlege: dungeoneering, knowledge: engineering and disable device rolls.

That's all I've thought of so far.
