Helix shrinks by dashing, and stretches out when jumping! This flexibility makes it difficult for opponents to land their attacks. #ARMS pic.twitter.com/jq2t1jicNi

It seems when he stretches out its actually his first jump. I wasn't sure at first because he double jumps almost immediately a couple of times in the clip. The puddle dash was obvious. I'm assuming when he is dodging all those hits at the end its actually him blocking too.
It seems when he stretches out he can stay like that indefinitely, but his feet remain stationary and you can only move the upper body.
