Not that Jean calls it that, mind you: he much prefers "Quicksilver". Unfortunately, he didn't discover this Song, so he doesn't get to dictate the formal name.

The Song allows the singer to essentially mold and stretch his, her or its flesh for ten minutes (one hour at level/4 and above). For each level of the Song, the subject may stretch out 12 inches. 'Hand to hand' attacks have a -2 to Power, but +1 to Accuracy: the negative modifier goes away at level/4 and above. At any level, the subject is infinitely flexible, can roll up into a literal ball, and so forth: note that clothing isn't affected, and the subject's body will attempt to go back to its original shape at the end of the Song.

If the vessel of the Singer is inorganic, they may use this Song to penetrate a substance of roughly the same composition: this can mean anything from +3 to hits inflicted to the same bonus in repair or maintenance rolls. This trick is unavailable to organic life forms, but the ability to mold your body so that you can see what you're doing for a change is usually worth +2 to repair rolls anyway.

Bonus: Lightning (Mending)

Available: Eli, Jean, (Jaymiel). Andrealphus, Valefor and Vapula would be good demonic candidates to have this Song, but it's too new as written.

This Song appeared as the result of a marathon cartoon-watching session between Francis, Mercurian of Creation, and his boss. They were watching vintage first season Super-friends, and had gotten to the episode where Plasticman showed up to retrieve a mouse from a computer. A chance comment from Francis about how his girlfriend could use repairmen with that ability ended up, six months later, with Eli teaching him the above Song.

Naturally, Francis gave it to Jaymiel (AA of Mending, and aforementioned girlfriend [long story]), who in turn gave it to Da... I mean, Jean. He's found that his androids find it very useful, and has even acted marginally less colder towards Francis as a result.

Marginally.
