Twenty seconds. That’s how long one Redditor spent drawing a mushroom with their finger: round cap, long stem, two dot eyes, a smile. It looked like a kid made it. Then ChatGPT turned it into a cute cartoon pet with a little green scarf, and a minute later it was blinking and smiling on a loop.
The whole thing happened on a phone. No design app, no editing software, no prompt wizardry. Here’s the walkthrough, based on u/Strange-Call5277’s real test in r/ChatGPTPromptGenius.
Why it matters 🍄
Some of us can see the picture in our head but can’t put it into words. Describing a character in a prompt is hard. Drawing a rough version is easy. A sketch gives the AI a shape, a face and a mood without you writing a paragraph.
The second half is the part I like most. You can save the character and call it by name in any new chat. Same face, same scarf, no re-uploading, no re-explaining. If you ever want a mascot, a pet for your brand, or a character for kids’ stories, that’s the real prize.
You only need the ChatGPT app. The poster says any plan works, free included.
How-to steps: doodle to looping GIF 🎨
- Open the sketch box. In the message box, type
@sketch. A “Sketch” option pops up above the box. Tap it and a blank drawing screen opens. - Draw your character. Use your finger. Keep it simple. When you’re done, tap the check mark at the bottom right (white tick in a black circle). The drawing attaches to your message.
- Ask for the image. With the sketch attached, send this:
Cute mushroom chatgpt pet generateSwap “mushroom” for whatever you drew.
- Wait about 30 seconds. The stick-figure mushroom came back as a shiny green cartoon pet with pink cheeks, big eyes, the same smile and a tiny scarf. ChatGPT even stuck its own logo on the cap and scarf, because the prompt said “chatgpt pet.”
- Ask for the GIF. Stay in the same chat and send:
Now make a looping animated gif out of it - Wait for the animation. The app showed “Worked for 45s,” then the mushroom started smiling and blinking on a loop. There’s a small “1×” button at the bottom left, which is the speed control.
- Download it. Once the text reply shows up under the animation, tap the “Download the looping GIF” link.
- Check the banner. When you see “Download complete,” the GIF is on your phone.
The doodle to GIF part took under 3 minutes.
How-to steps: save your character 💾
This is where the poster got stuck. Asking ChatGPT to save the character in the same chat didn’t work. It asked for the image to be uploaded again. So save the image to your phone first, then:
- Upload and name it. Tap the “+” at the bottom left of the message box, upload the image, and send:
save attached character as a referenceThen give it a name. The poster went with Mushpie. About 10 seconds later: “Mushpie is saved!” You can now call the character by name for new pictures, poses and animations.
- Call it in a new chat. Start a fresh chat, type @ and the name (like mushpie). Your character pops up above the message box, just like “Sketch” did. Tap it. The name appears in red inside your message with a tiny picture next to it.
- Tell it what to do. After the name, type your request. The poster used:
make it fly in clouds
The result was a GIF of Mushpie flying through a blue sky with white clouds and mountains below, eyes closed in a big happy smile. Same face, same green scarf, in a chat that never saw the original sketch.
Tips and tricks, plus where it breaks 🛠️
- Save the image to your phone before step 9. Skipping this is the one thing that tripped up the original test.
- Keep the doodle dead simple. A clear face and one or two features (a scarf, a hat) are easier for the AI to keep consistent than a busy drawing.
- One new idea per request in new chats. “Make it fly in clouds” worked well. Short, clear action, then iterate.
- No GIF showing up? GIFs are still rolling out to some accounts. If you only get a still picture, try again in a day or two.
- Usage limits are unknown. OpenAI hasn’t said how many GIFs each plan gets, so don’t plan a 50-GIF campaign yet.
- Be careful with real people. Only save photos of yourself, or of people who said yes.
Some ideas to steal: a mascot for your newsletter, a pet character for a kids’ bedtime story, a reaction GIF for your group chat, or a sticker-style avatar for your socials.
Your turn, Captain ⚓
Grab your phone, draw something silly in 20 seconds, and run the four prompts. Then name your character and send it somewhere new. It’s a small experiment, and the payoff is a character that sticks around.
If you try it, tell me what you drew and what you asked it to do. I’d love to hear what your Mushpie looks like!
