Oh my god. What is this craziness? This is amazing.
I think ‘Malstiftbehälter’ means “Terrible pencil case”. This thing is horrific. Yellow teeth, soulless yellow eyes, and that flip-top trashcan head that I think means it’s Canadian. Also the tiny crayons it came with are the worst crayons ever. Not even crappy restaurant crayon quality.
OH MY GOD LOOK OUT GILBERT
NOOOOOOOOO
This thing is insane. I’m giving it a place of honor on my desk, next to my Wooper figurine and Vault Boy bobblehead.
Look at that, he fits right in.
This totally makes up for the Messengeroos and the construction trucks. I love you, Kinder Eggs.

Hey, if you get some 3d glasses in another egg you can draw crappy 3d drawings :)
I think it actually means "crayon holder", which could be supported by the fact that it came with crayons. OTOH I like your translation better :)
