We study the optical fields that are produced by two collinear Laguerre-Gaussian (LG) beams in strongly nonlocal nonlinear media. Various novel kinds of rotating breathers and solitons, such as quadrangle, pentacle, pentagon, etc. can be obtained by combining different mode-index LG beams with the different relative amplitude. The rotating and translating asymmetric breathers and solitons can be obtained when the difference of the azimuthal charge between the two combining LG beams is 1.
