Help me identify the origin of this memory
I've never posted here so hopefully this is ok, but I am in need of answers after hours of fruitless searching. I am looking for a scene in a cartoon I watched as a child late 90s most likely 1997/8. (I would have been watching shows like, Franklin, Arthur, and little bear at the time.) I have a memory of a character finding an ordinary rock and putting it on a shelf. The rock ends up falling and breaking much to the main characters distress. Until they see the rock has broken in half to reveal it is a geode.
In searching for it I thought it could be the episode "Franklin collects" from the show Franklin about a cartoon turtle. I watched the whole episode it was not it. I originally was convinced it was from Little Bear but have found nothing when looking into its episodes.
Now, not only me, but my family is invested in me finding where this memory originates from. It must be from a 90s cartoon and that is why I am here.
