This is “Horse Laugh” by Kunsulu Jilkishiyeva from Nicholas Terry’s “Drawing Origami Tome 1” – a fun fold that sees some amazing box pleating and layer management to make a really detailed head (with lips, teeth, eyes, the works), tail, rather lovely mane and some funky legs.
This was WTF500 – amazingly no one guessed it, although some tried.
After the first collapse, we have a compound point, a couple of pleated stickey-outey things and a bunch of paper to hide creatively.
Next we bring the bundles of pleats up, organising gussets and layers as we go
After some working and re-working of the pleats at the other end we manage to extract two more stickey-outey things, before further shaping.
Many people think these are hard, but once you get it, the fold in development becomes staggeringly obvious, so get your thinking caps on and suggest what you think it is in the comments.
