Well, technically it's "waternoodle", not "funnoodle", but aside from some warning imprinted on it about kids and drowning and the dangers of eating non-edible items, it seems to be the same stuff.
Anyway, Grocery Outlet has some cheap, 60% off (so they claim), and I bought a bit extra, which is currently locked up in the car crying for a new home, so if anyone wants to buy any tomorrow, $1.00 a tube.
