Ep 16. Naomi's Evil Plot

After Kiyo goes to school, Zatch volunteers to do the shopping for Kiyo's mother. Ponygon accompanies him, and on the way, he notices that the park has become a mess. One of the playground children notices Zatch and tells him it is his fault. Zatch presumes Naomi has plans to take over the park. Zatch and Ponygon follow Naomi to a department store to find out her plan. They meet Tia, along the way, who joins them. After buying some products, Naomi realizes she has been followed, so she tells one of the employees that Zatch, Tia, and Ponygon are lost children. The three are then chased down by store employees who want to take them to the lost-child centre. They later meet up with Kiyo and Megumi. Zatch heads to the park and confronts Naomi. Using the things she bought, she defeats Zatch. Zatch prepares to go home and finds out Naomi has cleaned the park. Zatch arrives home and everyone is dismayed when Zatch confesses that he forgot to go shopping.
