Create an animated 3D image of an alpha particle, represented in a playful and colorful style, child friendly. The particle must consist of two bright, smiling protons and two happy neutrons, all holding hands in a circular formation. Protons may have a slight reddish hue, while neutrons can be a light blue. The background should be a soft and bright spatial environment, with light sparkles, giving the impression that the particle is floating in a friendly cosmic atmosphere.
