Future Plan:

Version 1.0.0

The Next Generation

• Add Inflatable Ender Dragon Girl, Inflatable Sylveon, and Inflatable Espeon.
• Use exp to unlock new abilities for your inflatable partners.
• 3D models for the items.
• Use guide book instead of achievements to introduce the game content.

I want to use this model but I don't know how to make them animated in Minecraft...

Version 2.0.0

Spirit of Craftsman

• Allow players to experience the production of inflatable toys in a relaxed way.
• Add multiple printing and heat sealing equipment, different molds, and show the strength differences of pinched and lapped seams.
• In the early phase, acquire STC templates during expeditions to print different toy patterns. You can craft inflatable toys with pinched seams using simple tools, then do inner strips reinforce through adhesive bonding at higher costs. During mid-late phases, manufacture Servo-skulls to fully automate professional RF welding equipment, so you can simply provide materials to obtain premium-quality inflatables– ​and don't forget regular Machine Spirit appeasement rituals!

Description:

• This mod add living inflatables that can be ridden and help in combat. 
• Your inflatable pet can be deflated and carried in the inventory, and can be inflated with a pump when needed. 
• Compared to horses in Minecraft, inflatable pets can make your travel more convenient, but be careful, they are very fragile, even the slightest damage can pop them. 
• Although you can create special equipment to protect your inflatable pets as the game progresses, they should still stay away from sharp things most of the time.

Riding Glaceon on water with armored Glaceon beside

• You can also make high-frequency redstone heat sealers or use organic solvents to make adhesives for making inflatable toys at home.
• This is a beta version, so only Glaceon available. More new creatures and features will be introduced in the future.
