when they start out on their journey. It took the basket of macarons that Serena
had baked the night before and began stuffing itself and didn't want to share them. Sophie
noted that Harimaron loves pranks.
Team Rocket captured Professor Sycamore
but Harimaron was able to follow a macaron crumb trail to their hideout. It was initially more concerned about getting the macarons back but it finally realized that Team Rocket was also a threat, so it helped out and manged to stop the Mega Mega Nyarth mecha.

in the crisis situation, the two began to bond and just as Clemont
was leaving Professor Sycamore
lab, it indicated that it wanted to travel with Clemont
. Professor Sycamore
Harimaron's monster ball and he got it.
