With the exception of MK8D, Blooper is super useless as an item. It was somewhat effective in Mario Kart 8 since it did a better job of covering the screen and also made your traction a lot more slippery.
But then it was downgraded even more in Mario Kart Tour because not only does it no longer make your kart slippery, but it's even easier to get rid of the ink. Any kind of boost, including trick jumps or mini-turbo boosts, will get rid of the ink. So it's more useless than ever before...
Afaik yeah the ink washes off only when you enter water.Does squid ink come off easily while underwater? That sounds like it would be pretty useless for squids…
I'm pretty sure the ink washes off if you enter water, though (correct me if I'm wrong)
