I enjoy spawncamping during Turf War, just standing a short bit away from the spawn point and splatting enemies as they try to leave. It's not that effective unless it lasts the whole match, and it's borderline meaningless on Kelp/Bluefin/Moray (Kelp due to the large spawn area being impossible to cover with just one Inkling, Bluefin for the difficulty of reaching the spawn point and the ease of which you can splat Inklings who wait just outside the spawn area, or at least it felt that way during Splatfest #2, Moray due to the length of time it takes to reach the spawn point making it so you only have half the match to camp at best; but all of that just makes spawncamping those maps feel better), but it's really fun to get a few splats on enemies as they leave their spawn, and my teammates can handle inking the rest of the map (plus I already inked quite a bit of the map just getting to the spawn point, generally).
It's especially effective during Splatfest, for some reason. I can actually lock teams down there, whereas the rest of the time someone always slips by or I get splatted fairly quickly.
Also, jumping onto the trash cans by Spyke and going from there to the balcony by jumping. Completely pointless, but I like doing it after I visit Spyke.
