With kids that fib (which most do at some point), a great idea that we got was the “truthtellers club”. Basically you make two boxes – one for the “truthtellers club” and one for what we call “the fibtellersclub”.

We got a ton of art supplies and two boxes. We made one wonderful and happy, the other dark and bleak. Hayley got to made the decision on what goes where, etc. I helped her with it some of course. Then you make figures of each of the people in the house with their photos.

You put it somewhere reasonably visible someone lies, you silently just move them from the “truthtellers club” to the “the fibtellers club”.
