Moons can have moons but probably not for long due to orbital perturbation.
Artificial satellites around our moon need some form of propulsive station-keeping to hold them in place, but our moon also has notoriously lumpy gravity corresponding somewhat to its distorted spherical shape (the 'heavy' side always faces us, being tidally locked).
The ring around Planet Custard is evidence suggesting that it itself had a moon which has now passed beyond the Roche Limit and disintegrated. A moon having a moon is already pushing at the envelope of credibility, but a moon with a moon with a moon is clearly a step too far.
The orbit of 'planet' Custard would need to be tidally locked to the Moon's far side in order to remain hidden from Earth view. Unfortunately the orbital height required for a selenostationary orbit is well beyond the Hill sphere radius, and so is orbitally unstable.
The Earth-Moon L2 Lagrange point is the obvious ideal location, but as any fule 'no, Lagrange points L1, L2 and L3 are also unstable.
In order for Planet Custard to remain there for any meaningful period of time it must have its own propulsive system.
Obviously this is the cause of the custard rain, as the planet squirts custard out as an orbital manoeuvring/reaction control system, and that custard either falls to the moon, or is slung around and escapes the Earth-Moon system, or de-orbits on Earth.
Unless Planet Custard has some exotic method to create infinite custard from sunlight (or zero-point energy or something), it cannot last very long. Years, decades, centuries maybe.

projectile custard, hmm not sure if this suggests some planet/comet hybrid
the custard made from sunlight sounds promising since as we all know both custard and the sun are yellow, surely no coincidence.

Not be confused with the18th century medical expression 'it falleth like custard rayne'
referring to a discharge of pus observed in one of the advanced stages of several transmitted diseases suffered by women
