Battle roomba and sand in the eyes could be the alternative name of these spells, but they do more caustic damage than that.
Pungent Cube could have simply been a summoning of gelatinous cube, but I feel like it makes the spell less interesting, since the cube doesn't move that fast, and this is a fun new way of restraining your foes, and burning their face off at the same time.
Melt Sight is simply an alternative spell to blind enemies which also makes use of acid, a damage type that really doesn't have that many official spells.
If you want to catch 5 more acidic spells, you can find them on Patreon (alongside 600 pages of D&D content).
