The mom
Lisa, the feelings translator
While Ddey tries to fix everything with a joke, Lisa gets down to Billy's level, validates what he feels and helps him put a name to it.

The family's anchor
Patient, a peacemaker and strong-willed, Lisa holds the family together. With Billy being a bundle of shyness and Ddey swinging between playful and grumpy, she's the one who keeps the boat steady — and the one everybody runs to when something goes really wrong.
A modern mom, a real mom
Lisa juggles work, the house (which turns into chaos with Ddey and the robot brothers scattering junk everywhere) and her son's feelings. Surrounded by all that weirdness, she's developed a slightly dry sense of humor — but it always comes with love.
Favorite things
- Creative cooking: colorful slime cakes and cookies that calm the jitters.
- Gardening: she grows strange, beautiful plants (and the snakes in her hair love them).
- Monster psychology: she always has a book tucked under her arm to better understand Billy, Nick and Stu.
When she's not at the clinic, the kitchen becomes her second office: it's where she mends shy hearts while the kids play.
