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.
Why stickers, not more books?
We kept hearing the same thing from parents:
“Tutu has become our whole family’s nickname for our daughter. Even grandma asks, ‘Did Tutu eat properly today?’”
That was a strong signal. When readers carry a character out of the book and into their daily life, she stops being a character — she becomes part of the family.
LINE stickers are the fastest way to lean into that. In Taiwan, the highest-frequency family communication channel is the LINE chat window. Tutu belongs there.
How we picked the 24 phrases
We didn’t want “stickers a designer thinks look cute.” 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:
- CHARACTER LOCK: a fixed 5-line character description at the start of every prompt
- 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
- 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.
For readers who buy within the first 24 hours of release, we’ll email a hand-written “Tutu phrasebook” PDF — English translations + situational usage for all 24 phrases — as a thank-you to early supporters.

What’s next
If “Tutu’s Daily” does well, Ban-Ban (Tutu’s little brother) gets stickers next. Then Amy, then Bobo. Amy & Bobo’s full ensemble will move into your LINE chats, one character at a time.
But we’ll watch the data first. Ship one, listen, then decide on the next. Same way we make the picture books.
