In my previous game, my first triplets also disliked running (and sunlight). I found it quite funny though; especially when they were playing tag. Three snail boys Kei-Kenoi-Kenobi attached together, played tag in a slow motion for hours. It's true that they were quite useless, but I let them live in their own world. I've just checked that game for their progress, and to my surprise all three have become master scientists and almost master farmers. If I didn't fill my esteemed elder quota, I could easily master them in parenting as well and provide them with nice looking totems.
