Where is Poirot when you need him?

There has been aSuperlambbanana theft in our office. Quite magically, three of our green Superlambbananas have disapeared from the office. 

Where are they? I DO NOT KNOW!

I am less than happy, in fact earlier on, I let out a scream of fury. 

If you know their whereabouts, please do let me know. I have my suspicions, in fact, I am convinced I know exactly who has nabbed our miniture friends. So, if the culprit is reading this, trust me, they will be returned, or else. 

You have been warned.
