Abstract: A rotary displacement structure of a fun device includes a container body. The container body has a space therein. A fluid is provided in the space. A rotary displacement unit is disposed in the space. The rotary displacement unit has buoyancy or gravity. The rotary displacement unit includes at least one blade assembly. When the container body is overturned, the rotary displacement unit will rise or descend through buoyancy or gravity. At the same time, the blade assembly enables the rotary displacement unit to rotate when ascending or descending, so as to obtain a different visual effect from the prior art.

Abstract: A protruding tongue and sounding structure of a puppet includes a protruding tongue and sounding device mounted inside the puppet. The puppet is a soft and hollow bag-shaped configuration. The protruding tongue and sounding device includes a housing and a slide member which is movable in the housing by air flow. A whistle is provided in the slide member. The slide member includes a tongue at one end thereof. The tongue can extend out of the slide member and the puppet. When the puppet is pressed by the user's fingers, the air in the puppet flows out through the protruding tongue and sounding device. The air in the puppet pushes the slide member of the protruding tongue and sounding device to move outward and forces the whistle to sound. Furthermore, the tongue extends outward, like the puppet to protrude its tongue.

Abstract: An internal rocking structure applied in eyeball of the puppet includes an outer casing made of a transparent material, an inner casing, and an elastic member; the inner casing being connected to the elastic member, which is connected to a bottom of the outer casing; a pattern of an eyeball being printed on where appropriately on the inner casing; upon shaking the rocking structure, the elastic member maintaining the inner casing in a rocking status for a given time to deliver amusing effects of a rocking eyeball and significantly increase bizarrely lovable effects when applied in a puppet or doll.

Abstract: A deformable toy includes: a deformable surrounding wall defining an enclosed space therein and having a foldable portion and an invertable portion; and a decorative piece connected to the invertable portion. The invertable portion is concave relative to the foldable portion so as to cooperate with the foldable portion to define a first recess to receive the decorative piece therein when the foldable portion is disposed at a non-folded state and the invertable portion is disposed at a non-inverted state. The foldable portion defines a second recess, the invertable portion is convex relative to the foldable portion to protrude outwardly of the second recess from the foldable portion, and the decorative piece is disposed outwardly of the second recess when the foldable portion is disposed at a folded state and the invertable portion is disposed at an inverted state.
