I heard this story when i did lunch with an imagineer
The imagineer that came up with the idea to add mr. Toad to the pet cemetery still works for disney
He pitched the idea to his boss, and the idea sat on a shelf for a few years
When he pitched it again, we was given approval but no budget
Since he couldnt pay for a custom made statue in his budget, he instead found an old mr. Toad garden gnome from
disneyland that was discontinued for sale from a gift shop a few years prior
He snuck in at night after the park closed and personally dug the hole and built the foundation for the statue without telling anyone about his plan
He waited until the night before halloween to install the statue
"Mysteriously...." The toad statue appeared the morning of halloween
He said the cast members on the mansion thought someone was going to get fired for messing with the cemetery!
He also said that morning one of the trainers that worked on the mansion for years gave a tour to new cast members and stopped dead in her tracks when she saw it! She thought it had been covered by bushes and just hadnt seen it!
After letting rumors fly for a while (few hours or days, i forget), he finally came clean and wrote it into the attraction's back story
