DIY Baby Toy Concept Sheets

Please generate 4 concept-sheet images for handmade DIY baby toys using the theme "{argument name="Theme" default="plastic bottle"}." Important: Please generate the 4 images as separate images. Draw only one toy idea per image. Do not put multiple ideas into a single image. Grid layouts, collages, 2x2 splits, and comparison-table layouts are prohibited. This is not a design for a commercially sold baby toy. It is a DIY toy that a parent/guardian can actually make by hand using materials that already exist at home. Do not make it look like a finished product that an individual couldn't make, a mass-produced item, a product with dedicated parts, a silicone-molded item, one made with special molds, or a luxury toy in a product-design style. If the theme is "plastic bottle": Instead of a new product styled to look like a plastic bottle, make it a DIY toy that directly uses an actual empty plastic bottle as is. Make it look like the original plastic bottle shape, a transparent bottle body, the existing cap, the look of a peeled-off label, and visibly hand-wrapped vinyl tape or masking tape. Give it the feel of something that can be made using only materials available at a 100-yen shop or at home. Make the content of the 4 images each a DIY toy with a different way of playing. Image 1: A DIY toy for enjoying sound Image 2: A DIY toy for rolling and chasing Image 3: A DIY toy for looking and observing Image 4: A DIY toy for touching, gripping, and enjoying texture Please include the following in each concept sheet: ・The main visual of the completed DIY toy ・A usage scene of a baby playing with it by hand ・A list of materials used ・A simple 3-step how-to-make diagram ・A diagram showing the materials and structure ・Safety diagrams covering cap fixation, sealing, leak prevention, and damage checks ・Play-method icons ・Points that promote development Safety conditions: Target age is 6 to 18 months. Always depict it as a DIY toy to be played with under a guardian's supervision. If small materials are used, they must always be completely sealed inside the bottle or bag. Do not attach small parts to the outside that could easily come off. Depict the cap and any openings as glued shut and then firmly secured on top with tape. Small parts that are a choking-hazard size, sharp parts, fragile/breakable materials, and long strings are prohibited. Scenes of the baby putting it in their mouth, biting it, or licking it are prohibited. Visual style: White background. Gentle natural light. A style like a handmade-toy recipe for nurseries or homes. A style like a DIY craft instruction sheet. A realistic look that seems easy to replicate. A finish with a bit of a handmade feel. Materials should be familiar and inexpensive. Do not make it look like a premium baby-goods brand. Do not make it look like a product rendering. A cute, clean, and approachable atmosphere. Keep text minimal, and center it around diagrams and icons.
