Does anyone remember the name of the cartoon?

I’m trying to remember the name of the cartoon from 2000s. It was a French (I think) 3d cartoon about a group of animals trying to solve some mystery. It had a gray dog that talked the most (seemed to be a leader) and a mute yellow chick that had no name and did the most of the job. It had a scene where they forged a key by melting something. Some details might be wrong but no-name chick is 100% was there (don’t remember if he was actually mute or not)
