Arpi - what to do with him?

[Arthur Dent]

leach ( P ) Pronunciation Key (lch)
v. leached, leach·ing, leach·es
v. tr.
To remove soluble or other constituents from by the action of a percolating liquid.
To empty; drain: "a world leached of pleasure, voided of meaning" (Marilynne Robinson).

But sure, leeched, as in a blood sucking invertabrate works well too.
