Yes, with water it will be slippery but they are not easier to break they become stretchy & stickier, search mochi soup japanese people eat it every new year as tradition but there are few cases of death because some still cant properly chew it and choked to death, mostly elder people. There are rice flour but for mochi always use pounded sticky rice . Similar like tteokkbokki with sauce. As for ramen there are reason why tteokbokki and mochi was made into bite size they are tough to chew making noodles of them you'll get tired after chewing awhile. Rice flour on the other hand can become rice noodles but its not mochi since it doesnt come from fresh pounded rice and lacks the consistency of a mochi so easier to chew most restaurant use this
