((Maybe you could enlist the services of a lightning mage and electrify the water?
Or just acquire a large amount of poison to dump into the area the gub are in. I'll admit, I haven't been following all other storylines terribly closely, so this might be completely unhelpful for all I know.

Timothy managed to pull himself together somewhat. This Lenny fellow was certainly quite reassuring.
"Yeah... I gotten losted a whiles ago an' ends up in Blynn. Been losted a real long times, not much sure where I's come from," the ghost said, wracking his brains for a name for that far-off, half forgotten land of sunshine and smiles where he'd wandered happily before ending up in the Other-place,
"But I knows dat I had a friend names Mister Bob there! And 'nother one called Hansel. Hansel weared all feathery-stuff, an' Mister Bob is had lotsa scary-crows on da garden..." He trailed off and peered hopefully at Lenny, wondering if perhaps the man had heard of them. He doubted it, though. he didn't know much about this place, but he was sure it was far away from anywhere he'd been before. If only he could remember the name of that place where he'd met Bob... He had trouble remembering things from one minute to the next, much less from that long ago.
"Dis Blynn place is seems real-nice, though," Timothy said, remembering his manners,
"I's sure you does realgood job of safe-keepin' it!">Tell Lenny about how I got lost and ended up here in Blynn.
>Try my best to remember the name of the place I came from, before all this scary interdimensional travel and other such distracting nonsense.
>Either way, follow Lenny. He seems nice.
