not so fast!

Bit tricky, this one. Not sure if it's possible using logic alone. Needed a lot of guesswork.

It's a snail, with the right antenna starting in the top right corner.

Hints:
r5 c5/9-11/14/18/22
r10 c5/7/10/13/16/18/23
r15 c8-11/14
r18 c1-22.

R15 should be c8-11/24.

Why do these people who think they can just draw anything try to solve their creations themselves first.

Thank you.

Not my actual time! It took so long I decided to do it again to at least get some points for my pain. Pile of crap.
