* ue_t0 needs to be as close to body load as possible.
* - ue.tag maps to URLType dimension of OnlineQueryLog in PMET. Because we cannot add

"Petula is a beautiful cow who smells nice, has pretty hair, and makes Ariol tremble when she's around. And even though Ariol's story so far is almost 400 pages long, he still hasn't worked up the courage to tell Petula that he loves her! Instead, he keeps accidentally saying all the wrong things every time she turns around to talk to him in class. Valiant Ariol is finally ready to make his move. Will he soar like Thunder Horse or plummet like, well, like Ariol?
With charming artwork and hilarious vignettes, Ariol is the perfect series for anyone who started off life as a kid!"
