Manick Mansion (no, NOT Maniac Mansion)

[Radiant]

Hi there,

I was playing this German MM clone (called Manick Mansion, also the entire game is in German and it has a very different house than MM does, even if the mad scientist premiss is the same).
Anyway how do I get past the cactus?

I found a walkthrough for it  :o 
But it is all in German, so you'd have to babelfish (or alternative) to translate  it 
I'm going to send it to you!

Ich spriche Deutsch, das ist kein Problem. Bitte senden sie mir den Laufdurch. Danke schon.
