HELP Custom robo arena (dono were to go)

i just win the battle between bull and won the champion and now were to go tell me plzzz

According to gamefaqs: You get the Tournament Award.
Tell Dennis you're ready, and then walk all the way left to NeoBrain, where
your sister and dad both work. Talk to the receptionist, and then head
upstairs and talk to that receptionist. Press A on the elevator and look
around the building. See the kid with blue hair in the left room. Yeah. Well
remember his face, because you'll face him soon enough. Talk to Liv, Dennis,
and then Kindjal, the purple-haired scientist. Head to Pop Pop after you do
this. Then get ready to face the computer, bum bum bum, bom bom. Weird
ominous music sounds

kk thanks

No problem :) glad to help.
