Badtz-maru
Location
Fish Whisperer AbilityUnlocked after Friendship Level 5
Gamer Ability
Unlocked after Friendship Level 9
Badtz-maru runs the 
Comic and Bait Shop on the pier of 
Seaside Resort. He will help you learn to make both the 
Fishing Rod and the 
Net. He'll also reward you with materials if you release fish with him.
Personality
"Badtz-maru is one mischievous penguin. He’s excited to soak up some rays, surf some waves and catch some giant fish while on vacation! But something weird is happening on this island, and even though he’s easy-going, he’s determined to uncover the mystery."
— Badtz-maru's character page on the official Hello Kitty Island Adventure website
Badtz-maru's biggest hobbies are pranks, comic books, and fishing. As for the fish themselves, he might enjoy releasing them just as much as catching them! He ends up running a Comic and Bait Shop on the docks. If there is a mystery afoot, however, the Fancy Pants Detective Agency is sure to be on the case.
In several of 
Kuromi's possible daily strike-up dialogs she discusses Badtz-maru. She refers to him by his full name Bad Badtz-maru, which she claims "explains everything". She also claims he considered himself a movie expert after watching one silent movie, and that she is defending herself from accusations by him that her middle name is "Mischief".
Badtz-maru's Birthday Celebration occurs annually in early April.
Gifts
The player can give Badtz-maru up to three gifts per day. 
Gifting gives Friendship XP (experience points), and enough Friendship XP will increase Badtz-maru's Friendship Level with the player. Gift limits can be reset by gifting a 
Friendship Blossom or using a 
Friendship Bouquet. Certain quests, such as any Daily Quests from Badtz-maru, may also reward Friendship XP.
While raising Friendship XP, players will receive 
Paper as a reward for each gift given to Badtz-maru. The amount received depends on the value of the gift and increases by 1 at Good Friend and by 1 again at Close Friend.
If the player has reached maximum friendship level (
Best Friend status) with Badtz-maru, they will instead receive 1x 
Badtz-maru Box for each gift given or Daily Quest completed. It will still contain Paper when opened.

Dialog Options
Badtz-maru has two unique dialog options.
Releasing Fish
Choosing the "Let's release some fish" option allows the player to release fish in exchange for a limited amount of currency materials daily. Only the first 10 fish per day give currency in return. The amount of currency varies with the fish's rarity, and what currency the fish gives depends on what region it is from.
- See "Releasing Fish" for more information.
Ultimate Comics
Choosing the "Ultimate comics" option is only possible if the player has all issues of a comic in their inventory. This is used to make them into a complete set (also called an "ultimate comic").
- See "Complete Set (Comics)" for more information.
