Okay its more easier show this in video than explain its. But yes its pretty similar as Miner/Blocker glitch in DOS And SNES Lemmings. You very rarery need it. Im not know is this creator intentions. Yes you can pass through floor. No worry its not work neolemmings.

Looks like this is caused by the "Dangler" animation, which NeoLemmix doesn't have? Meaning, that Danglers can dangle through terrain.
Yes, this is indeed a Dangler bug - I've updated the topic title to reflect this.
It seems that the following conditions have to be correct in order for this to happen:
- Terrain platform must be no more than 1px high
- Dangler's foot position must be no more or less than 1px higher than the platform (meaning a 10px gap between platform and Dangler's hand)
