Custom Bubble Blow Plush Toys

These plush toys have a bubble inside that can be blown out when you squeeze them.

Initially, the bubble is about the size of a soybean, and with a bit more pressure, it grows to the size of a coin. The largest bubbles can be as big as an egg.

You can play with them vigorously, but they are quite tough to pop. However, avoid touching them with sharp objects like needles, or they might burst instantly.

Additionally, can you guess which character from the game "Genshin Impact" inspired the designer when creating this bubble feature?
