It seemed everyone was too busy with the lesser hollow to pay Ujauja any mind. Perfect.
He went on the hunt. He had a perfectly cruel little tactic. Whenever a shinigami was fighting alone Ujauja would skitter out of a corner and quickly tear him apart before its opponents could finish him. After that he'd fight the hollow, but not to kill. As soon as he got a good bite out of every one he'd make his escape.
It wasn't a very well known fact, but Ujauja knew of a very interesting little fact about Hollow transformation.
[i]Once eaten, a hollow can't grow.[/i]
With those bites the hollow are marked and when they die their souls are taken by the offender. 
Unless the bitten eats the biter the bitten is incomplete, it can't grow and advance to the next level.
With every ambush and bite another hollow was doomed to never see himself become a Menos. And should they die, even by shinigami hands, Ujauja got the spoils.
The prospect of this horrible misery he was inflicting made Ujauja all giddy with anticipation, it wouldn't be long for the first harvest to start.

After he lost count he sat down on a tall industrial chimney and took in the scenery of death and destruction bellow.
He stared down at the mayhem and spotted Soi, and later Ken'ichi. He watched them in silence, while he picked his teeth with a broken zanpacto.
