The ultimate Ultimatrix

First off. A pox and a damn off on the makers of the accursed cartoon
serial Ben 10. Now having got that off my rather substantial chest, I
can get down to ranting in a somewhat sane manner.
So the brat decided he wanted an Ultimatrix. He already has the
Omnitrix. Millions of them dismembered all over the house. He began
his whine whine whine whine process which is guaranteed to get mamma's
hair frizzing up in classic finger in electric socket manner and head
with the level of migraine that requires hammer to subdue.
Finally, when dadi returned from her trip to the native land, she
handed over largesse to the brat and told him to go buy said
Ultimatrix as a gift from her. He bounded in joy to the cupboard and
began getting dressed to go to the mall to buy said Ultimatrix.
Mamma followed reluctantly, aware that colossal waste of money was to
ensue. Sure enough, when Mamma read the price of said fancy plastic
wrist strapped device, she fell to the floor and had to be roused by
the smelly socks of the sales staff who hovered around looking very
worried. No brat, said Cruella de Ville mamma, this is ridiculously
expensive. Buy something worth it for that money. The brat sobbed fat
tears that would have earned him an Uncle Oscar had he been doing it
for camera. He rolled around on the aisles. He thrashed. Mamma
seriously considered putting him up for adoption.
Anyway, Mamma was migrainey and easily worn down. The Ultimatrix was
worn. The fancy watch type thingie worn. The brat bounced from end to
end like he had giant springs on his shoes or the force had entered
him, mamma despatched him downstairs before any furniture bore the
brunt of his joy.
Mamma sat down in deep contemplation wondering what it was about the
darned Ultimatrix that gave him the joy it did. Well, a small niggling
voice of conscience said, it could be his equivalent of the LV bag.
