Help! I Am a Prisoner in a Toothpaste Factory

As Ronnie is cleaning his teeth one morning, he sees a message written in the toothpaste: "HELP!" it reads, "I AM A PRISONER IN A TOOTHPASTE FACTORY!"
Later, there is an even more urgent appeal: "HELP! THERE IS NOT MUCH TIME!"

So, with the somewhat dubious help of Uncle Roger, Ronnie sets off on the toothpaste trail, desperately trying to avoid the wicked clutches of the chemist.
But when Mum and Dad are imprisoned in Glum's Toothpaste Factory, Ronnies mission becomes even more dangerous.
Can he solve the whole extraordinairy mystery before he, too, becomes a prisoner?
