Creating Tutu's stickers

We turned Tutu — one of our picture book leads — into a 24-piece LINE sticker pack. From "good morning" to "hug" to "you got this", made to reply to messages.

Creating Tutu's stickers

Starting this month, Tutu is officially landing in your LINE chats.

We turned Tutu — the curious little girl from Amy & Tutu’s Summer Watermelon — into a 24-piece LINE sticker pack called “Tutu’s Daily — Family Chat Pack”.

From good morning to good night, from “let’s eat!” to “hug”, 24 phrases families say to each other every single day.

How we picked the 24 phrases

We wanted conversations families actually have.

So we grouped 24 phrases into three buckets:

  • Time: good morning, good night, heading out, I’m here, almost home
  • Meals: let’s eat!, I’m hungry, want to share?, drank water yet?, breakfast time
  • Feelings: hug, miss you, love you, I get you, you got this

The rest are high-frequency reactions: OK got it, sure sure, roger, haha, sob sob, sorry.

Every Tutu pose matches the book canon exactly — bangs, twin tails, pink ribbon, pink t-shirt, light denim shorts. If you’ve read Summer Watermelon, this is the same Tutu.

The hardest part wasn’t drawing

It was keeping all 24 Tutus identical.

AI image gen’s biggest weakness is “character drift”: run the same prompt twice and you can get two completely different girls. To keep all 24 stickers as the same Tutu, we did three things:

  1. CHARACTER LOCK: a fixed 5-line character description at the start of every prompt
  2. Baked-in captions: the AI paints the Chinese text directly into the canvas, no post-processing overlay, so the text blends right into the hand-painted style
  3. Side-by-side comparison: every output is diffed against a “Tutu baseline” reference; off-model = regenerate

We re-rolled 8 stickers before all 24 passed.

Coming soon

The pack already passes internal LINE spec validation (24 stickers + main image + tab image, all within size and resolution limits). Next stop: LINE STORE review.
