Albi has come up with a great birthday gift for his mother! Unfortunately, he needs more money than his piggy bank can provide. Luckily, Egon Krumpfling, Albi's adorable little friend with the green fluffy fur, knows exactly how to earn some quick cash: the two of them take one of the many handbags from Grandma Krumpfling's collection and sell it at the flea market. However, they have no idea that this will lead them into a lot of trouble and even put the Krumpf Castle in danger.
