Tiger and the Mandy Cup Challenge
Tiger wants to make his debut at the Mandy Cup but everyone is worried that he won't be able to do it without his abilities (which he has forgotten). Genki tried to teach Tiger some defensive moves but Tiger insists on continue practicing alone to receive his abilities. So, Genki and Tiger broke out into a fight and when they enter for the competition the next day, Tiger refuses to be coached by Genki. The competition format is 2 monsters per team and 1 on 1 battles. If there is a draw, a 1 on 1 Sudden Death round will be held determine the winner. Despite not having their more powerful moves, Tiger and Mocchi were able to win their rounds and made it to the finals. Their opponent is a mild looking boy who acts strangely innocent. Tiger took on a Snail named Knight Nighton but found that his attacks were all useless and lost badly as he could not defend himself. After a tough fight Mocchi defeated his opponent, a much larger Mocchi Type monster and brings the match to Sudden Death! With Mocchi too tired to continue, Tiger volunteers and decides to listen to Genki but will that be enough to win?
