Inkrail
From Inkipedia, the Splatoon wiki
The Inkrail is a form of transportation and mechanic in Hero Mode.
Description
Inkrails appear to be long, thin ropes of Ink that connect various platforms in Octo Valley. They are tethered to such platforms by slightly larger bulbs, serving as entry points for Inklings. When in squid form, Inklings are able to travel back and forth along Inkrails as they please; however, if an Inkling jumps or uses its humanoid form while on an Inkrail, they will fall to their death.
