Imagen Halloween searches usually mix two Google tracks: DeepMind’s Gemini Image family (publicly nicknamed Nano Banana) on deepmind.google/models/imagen, and Google’s seasonal how-to for Nano Banana Halloween stills plus Gemini Halloween prompts, Photos Remix, Mixboard, Veo, and Canvas (Google Keyword blog, Oct 24, 2025). This guide stays on generation playbooks and official prompts, not a scrapable image gallery. Checked October 31, 2026.

Product names below appear on those official pages. This article does not invent unannounced model version numbers or promise that a pasted prompt will look identical for every account.

What “Imagen” Means on Google’s Pages Right Now

DeepMind’s imagen model hub currently titles the family Nano Banana and describes Gemini Image models built on Gemini:

  • Nano Banana 2 Lite — fastest, most efficient Gemini Image model in that lineup; high-speed generation and editing at the lowest cost tier described there.
  • Nano Banana 2 — described as Gemini 3.1 Flash Image with pro-level generation and editing at Flash speed.
  • Nano Banana Pro — built on Gemini 3; studio-quality precision and control for create and edit jobs.

Capabilities called out on that page: multimodal understanding (image + text instructions), conversational refinement, and real-world knowledge from Gemini reasoning. Prompting advice: specify characters, setting, and overall feel in detail.

Separately, Google Cloud’s Vertex AI docs describe Imagen on Vertex AI as a text-to-image stack for developers, with model IDs in the Imagen 3 and Imagen 4 lines (for example imagen-3.0-generate-002, imagen-4.0-generate-001, imagen-4.0-ultra-generate-001 on the Vertex image overview). Consumer Halloween tips in the Keyword blog speak in Nano Banana / Gemini / Veo product language, not Vertex ID strings—use the surface you actually open.

Nano Banana Halloween and Gemini Halloween Prompts (Official Blog)

Google’s Oct 24, 2025 post, “Try these tips and prompts for spooky AI images,” groups five activities. Summarized from that post only:

1. Spooky stills with Nano Banana

Examples the post walks through:

  • Turn a selfie into a Victorian ghost with a long prompt that asks for a semi-skeletal spectral translucent Victorian ghost, Victorian clothing, maintained pose/framing, ultra-realistic black-and-white Daguerreotype / wet-plate look with streaks and stains.
  • Build a Y2K-style scary movie poster from your photo (shiny purple bedding, 90s landline, bedsheet ghost in a doorway, grainy night lighting—full wording is on the blog).
  • “Turn my cat, Sunny, into a cartoon character wearing a wizard costume,” then optionally continue in Gemini Storybook for a short illustrated narrative.

2. Google Photos Halloween Remix

  • Remix can restyle a photo (3D animation, anime, sketch, and newer styles the post names: Halloween Remix, Claymation, Pixel Art, Ukiyo-e).
  • Path described: Google Photos → Create tab → Remix → pick an image → choose the Halloween Remix style.
  • Footnote on that article: Remix is available to Google Photos users on Android and iOS in the U.S.
  • Android users in the U.S. can also try festive edits via Help me edit in the photo editor, per the same post.

3. Costume brainstorming with Mixboard

Mixboard (Google Labs experiment) is framed for exploring costume ideas for yourself, couples/groups, or pets when you want visual variants of a rough concept.

4. Short spooky or festive video with Veo

  • The post references Veo 3.1 for stronger prompt adherence, richer audio, and more narrative control than earlier Veo wording in that article.
  • Workflow: animate a still, or describe a scene from scratch.
  • Non-horror example prompt (paraphrase structure; full text on the blog): two named dog mixes trick-or-treating in a leafy neighborhood with porch pumpkins, ending on “Happy Halloween!”, ≤30 seconds, cute sketched style.

5. Pumpkin carving templates via Gemini Canvas

Ask Canvas to “make an app that turns my selfie into a jack-o’-lantern and gives me a design I can carve at home.” The post notes the carving and cleanup stay on you.

Prompt Patterns That Match Official Advice

Pulled from DeepMind’s prompting note plus the Halloween blog’s examples—not guaranteed outputs:

  • Lock identity: “Maintain existing pose and framing” when editing a selfie.
  • Name the photographic process: Daguerreotype, wet plate, grainy 90s album, disposable camera.
  • Stage the scare: translucent ghost, dim hallway, bedsheet ghost in a doorway.
  • Keep seasonal props concrete: pumpkins on porches, falling leaves, “Happy Halloween!” end card for video.
  • Iterate in chat: DeepMind highlights conversational refinement; the blog chains Nano Banana → Storybook or Nano Banana → Veo.

What This Page Does Not Claim

  • It does not treat third-party prompt galleries or stock “Imagen Halloween” image packs as Google outputs.
  • It does not assign unpublished version numbers beyond names printed on DeepMind, the Keyword blog, or Vertex docs at check time.
  • Availability (which Gemini surface, Photos region, Labs experiment access, Vertex project quotas) depends on your account and region; Remix’s U.S. Android/iOS limit is the only regional gate the Halloween post footnotes.
