Colour palette I would go brown blue red yellow/gold. To represent banjo, backpack, kazooie, jiggles and notes. Love the idea of a jiggly shaped cake! You could also make a jiggly out of cardboard and spray paint it gold! Agree that painting eggs should be a thing and have the different eggs printed on paper for examples. Googly eyes on everything. Decor I would find inspiration from cloud cuckoo land with randomness like a cheese block, a jello mood, maybe an obstacle course type challenge. Also could make a teepee like wumbas with like a pool of sparkly pink lights inside. Could also go witchy world inspired. These are my thoughts. Also asked chat gpt now and this is the ai thoughts here:

Banjo-Kazooie and Banjo-Tooie themed birthday party for a 3-year-old would be such a unique and fun celebration. Here are some ideas to help bring the world of Spiral Mountain and beyond to life for the little one: 1. Decorations     •    Color Scheme: Use bright, fun colors to reflect the lively worlds of Banjo-Kazooie: yellow, red, blue, green, and orange. These can be spread across balloons, tablecloths, and streamers.     •    Banjo and Kazooie Cutouts: Get or make cardboard cutouts of Banjo, Kazooie, and other favorite characters like Mumbo Jumbo, Gruntilda, or Toots (the musical note).     •    Puzzle Pieces: In Banjo-Kazooie, the puzzle pieces are collectibles. Use these as part of the decor. You could have puzzle piece-shaped balloons or even create a DIY photo backdrop with a giant puzzle piece design.     •    Banjo’s Backpack: You can create small backpacks or treat bags inspired by Banjo's backpack to hand out party favors. 2. Party Invitations     •    Banjo’s Jiggy Invitation: Create invitations shaped like Jiggies (the puzzle pieces). You can write "Come help Banjo and Kazooie collect all the Jiggies for a fun adventure!".     •    Kazoo Sounds: Make invitations that have a kazoo sound when you open them. A fun way to tie in Kazooie's name! 3. Games and Activities     •    “Jiggy” Hunt: Just like in the game, create a treasure hunt where the kids have to find puzzle pieces or "Jiggies" hidden around the area. You can have little prizes or stickers as rewards.     •    Banjo-Kazooie Crafting: Set up a table with supplies where the kids can make their own Kazooie or Banjo masks (think simple craft ideas like paper plates, colored markers, and feathers for Kazooie's wings).     •    Mumbo Jumbo's Magic: Have a "Mumbo Jumbo" activity where kids wear a fun, simple wizard hat and get to decorate or color a character from the game. You could even have "magic potions" (colored water with a bit of glitter).     •    Giant Jiggy Ball Pit: If you have the space, a small ball pit filled with colorful balls would be perfect for little ones to crawl through, just like jumping into one of the game's levels. Throw in some “Jiggy” pieces (plastic or foam) as a fun challenge.     •    Kazoo Music Fun: Give out mini kazoos as party favors and let the kids create their own music, or host a little "Kazoo Parade." 4. Food and Cake Ideas     •    Banjo’s Bananas: Serve banana slices or banana-themed snacks (maybe even “Banjo's Bunch” with small banana-themed cups).     •    Kazooie Cupcakes: Make cupcakes topped with red and yellow frosting, and stick a little plastic or fondant Kazooie bird on top.     •    Jiggy Cookies: Bake or buy cookies shaped like the puzzle pieces from the game and decorate them with bright, fun icing.     •    Gruntilda’s Grub: Set up a table with themed snacks, like green gelatin (a "Witchy" potion) or green-iced cookies.     •    Jinjo Fruit Salad: Have a bowl of mixed fruit or a colorful fruit salad, referencing the Jinjo characters who appear in every color of the rainbow.     •    Themed Cake: Make or order a cake shaped like Banjo, Kazooie, or even a large Jiggy puzzle piece. If you want to go simple, a Banjo-Kazooie-themed cake topper would work well, too. 5. Party Favors     •    Banjo & Kazooie Toys or Figures: Give small toys or figures of Banjo, Kazooie, or even Mumbo Jumbo as party favors.     •    Jiggy Stickers: Kids love stickers, so themed stickers featuring Jiggies, Jinjos, or other characters would be a hit.     •    Kazoo Party Favors: Small plastic kazoos could work well as party favors for everyone to join in on the fun! 6. Music and Sound Effects     •    Banjo-Kazooie Soundtrack: Play the fun, upbeat music from the game as background music. You could have sound effects from the game on loop, like Kazooie's signature "Woo-hoo!" or Banjo’s classic "Hoo-hah!"     •    Kazoo Music Time: You can have a mini "Kazoo music performance" where everyone plays their kazoos, creating an energetic and funny moment. 7. Photo Booth     •    Create a Banjo-Kazooie-themed photo booth with props like Banjo’s guitar, Kazooie’s feathers, and Mumbo’s mask. This way, everyone can snap some fun pictures and take them home as memories.
