This is clearly Caterpie using string shot.

I came here hoping to read more about this worm and its slime guns but no one did much yet so i had to look it up and now I've become the commenter i hoped to find? I hope the mildly interested people following after me find this cool:

The slime is incredible stuff. It leaves the worm’s nozzles as twin streams of sticky liquid. But once it touches the target, it hardens almost immediately into a stiff, hard gel that is neither sticky nor soluble in water. It’s an incredible transformation and for the prey, it’s a fatal one. By ‘milking’ an Australian velvet worm called Euperipatoides rowelli and studying its slime, Haritos has discovered that its properties come from a special type of chaotic protein.

Chaos Bolt! Man this worm is cool.

Velvet worm used Slime Gun

It's super effective!

Honestly though those action shots are cool AF

It’s cool…but it’s not shark with lasers on its head cool

Imagine if those little fuckers were like 20 feet long.

According to Wikipedia it's actually a slime attack, so let's not get too excited. God's favorite beast is still probably the Platypus.
