Episode summary
A new soccer star named Roberto comes to Laura's school and quickly earns a reputation as a ""ball-hog."" He and Laura quickly come to be on bad terms when they bump into each other and he refers to Hamtaro as a ""rat."" When the ham-hams hear of Roberto's ""ball-hog"" ways, they set out to teach him a lesson, only to find that he's a tougher opponent than they thought. They also find out that he's a really nice guy, but seems to be acting tough. At another soccer game, Roberto acts huffy when he feels he isn't credited for winning the game, but a muttered comment suggests what he's really angry about.
