Tophat Gudetama, a recurring character in Hello Kitty Island Adventure, shifts its hiding place each week, with new locations becoming available every Monday. While initially central to quests like "The Laziest Egg" and "The Laziest Eggs" assigned by Pochacco during the game's early weeks, finding Tophat Gudetama remains a weekly activity even after these specific quests conclude. Pochacco will continue to remind players of the task at the beginning of each week.

To complete the objective, players must locate Tophat Gudetama and use the in-game camera to capture its image, similar to how other hidden Gudetama are documented. The character's varied hiding spots, totaling 52 across the island, can make it challenging to find without prior knowledge.

For the week of June 29, Tophat Gudetama is situated on a buoy located in the body of water to the west of Seaside Resort.

Successfully photographing Tophat Gudetama rewards players with the plans to craft Decorative Gudetama #4. It is important to note that Tophat Gudetama's locations are cyclical and repeat after all 52 unique spots have been visited. Given the game's release history, all these locations have likely cycled through at least once. Players who have been actively participating in the game may find that they have already photographed this week's particular Tophat Gudetama if they have already unlocked the corresponding decorative Gudetama recipe in their collections. A comprehensive list of all Tophat Gudetama locations is available on the Hello Kitty Island Adventure Wiki.
