Squeeze the plushie. Get the wisdom. Carry it to the top.
A Magic 8-Ball style app inspired by the beloved green plushie from PEAK, the co-op climbing game by Aggro Crab & Landfall.
Tap Bing Bong, hear a random voice line, and let the oracle of BingBong Airways guide your life decisions. Just like in the game, except you don't have to carry him up an entire mountain.
Bing Bong on the island, from the PEAK Wiki
In PEAK, Bing Bong is the stuffed plushie mascot of BingBong Airlines, the airline that crashes you onto a mysterious island. You can find him at the crash site on the Shore and squeeze him to hear a random voice line: a positive, negative, uncertain, or hilariously irrelevant response to whatever question you had in mind.
He weighs 5 points in your inventory. He gives you nothing useful. Players carry him to the summit anyway.
"Do not cast Bing Bong aside, it will remember."
For a brief time after PEAK's launch, the developers at Aggro Crab could actually possess Bing Bong and talk to players through him in real-time, jump-scaring climbers across the island. That feature was removed, but the legend remains.
BingBong Airlines, the worst airline, the best mascot
- 26 authentic voice lines: all the classic Bing Bong responses, from "yeah definitely" to "im not comfortable answering that"
- Real-time 3D Bing Bong: a fully 3D model rendered with the Filament engine (via
thermion_flutter), you squeeze the actual model, not a flat sprite - Drag to inspect in 3D: drag the character to orbit him freely, see his back, his feet, every angle; release and he eases back to facing you
- English / Português: a glass language panel greets you over the main screen on first launch; your pick translates Bing Bong's on-screen quotes, while the voice audio stays in his original English
- Shuffle-bag randomization: every voice line plays before any repeats, never the same line twice in a row
- Premium gamified physics: squash & stretch on tap (non-uniform scale), rotational wobble, spring-elastic button press
- Shockwave ripple emit: tapping Bing Bong sends an expanding ring outward, emitted from the character on every voice line trigger
- Dual-tone breathing halo: warm yellow + lime green aura that pulses (blur + spread oscillating) while speaking
- "I'm Bing Bong" button: dedicated button to hear his iconic catchphrase anytime
- Live quote display: Bing Bong's response fades and slides in centered on screen as he speaks
- Atmospheric stage lighting: blurred island backdrop + radial vignette + warm spotlight that intensifies on talk + drifting coral/cyan light leaks
- Typographic contrast: Daruma Drop One reserved for the character's voice (quote, "tap me", his name); clean system sans for UI chrome
- About sheet: glass bottom sheet with app info and a coral-glow link to the developer's GitHub
- Idle float + breathing: Bing Bong gently hovers and breathes (asymmetric scale) waiting to be consulted
- Immersive fullscreen: no distractions, just you and the oracle

Data flow: Tap → BingBongWidget triggers ShockwaveController.pulse() (visual) and CharacterNotifier.onTap() (state) → AudioService.playNext() → AudioRandomizer.next() → plays mp3 and returns its asset path (the quote key) → state goes to talking → _QuoteArea resolves the key to text for the chosen locale via localizeQuote() and fades/slides it in, AmbientGlow ramps up via _activeAnim, Background opens vignette and lifts warm spotlight → onPlayerComplete → state returns to idle and the halo fades out. The "i'm bing bong" button follows the same flow via playSpecific(), bypassing the randomizer.
Design system: generic UI primitives live in core/widgets/ (currently GlassPanel, SpringPressable). Feature-specific composition (animated character, halo, ripple, quote card) lives under features/character/presentation/widgets/. Color and typography tokens live in core/theme/ and app/app_theme.dart (kCharacterFont).

flutter build apkVoice line .mp3 files are not included in this repository. To run the app locally, place 26 .mp3 files in assets/audio/. Filenames become the displayed English quote text; underscores in filenames are rendered as apostrophes
(e.g. It_s a beautiful day.mp3 → It's a beautiful day).
Portuguese quotes are an override layer in core/i18n/quote_translations.dart (asset path → PT text). Lines with no entry, interjections like nahhh/uhhhhhh, fall back to the English base. The audio is never translated; only the on-screen text is.
PEAK is a co-op climbing game where the slightest mistake can spell your doom. Solo or as a group of up to four lost nature scouts, your only hope of rescue from a mysterious island is to scale the mountain at its center. The terrain changes every 24 hours. Over 11 million copies sold on Steam with Overwhelmingly Positive reviews (95%).
Developed by Team PEAK, a collaboration between Aggro Crab (Another Crab's Treasure) and Landfall (Content Warning).
- 3D model of Bing Bong by OFFDucky3D on Sketchfab.
This is a fan project. Bing Bong, PEAK, and all related assets belong to Aggro Crab and Landfall Games.
Made with Flutter and an unreasonable attachment to a green plushie.
