The best kinds of recreations are the ones that drive people to look up the source material.
This is one of those. It's a testament to their humor that even through limited sound, switching to Lego, (and thereby losing all facial expressions and some detail in props) and being recreated over 80 years later, it still brings smiles!
I love just how well you recreated the set and props. Plus, the timing on the gags feels spot-on.
If I'd suggest one improvement, it would be to find a way to display more of the victim's anger/panic. While he does wiggle back and forth, some extra turning of the head, slight arm movement, or even changing of the head to a more appropriate expression would have been a cheery on the top of this otherwise delicious sundae.
Still, great job!
