Stupidstein is also know as Brikolstein and has number CA for magic kinder

O look Stupidstein glows in the dark that is scary.

Stupidstein loves to eat books. Specially books with difficult formulas. But yeah he thinks he is an inventor so he needs to keep up ;)

This Kinder surprise toy from the monster hotel series is nice. It is easy to build an still strong and it glows (a little bit) in the dark.
