SOLVED. Children's fantasy, potion/lab kit, turn grandmother into a baby [s]

[Brittnee]

A brother and sister visit their grandparents I think on a beach somewhere. In the shed? Or shack or something they find an old laboratory kit with potions or something and make a potion that I think the dog and grandma accidentally take and they get younger and change into a puppy and baby and the kids try to find a cute before they stop existing.



Any ideas anyone??

I was looking for a similar (more current) thread to this, because I stumbled upon this:

Mr Bat's Great Invention
"A surreal comedy. When Granny swallows
Mr Bat's rejuvenating medicine, she
carelessly reduces herself to a six-year-old
and it's panic stations for Robert and his
friends as they try to undo the damage."

Just wanted to put it here in case someone's looking for a very similar plot...
