This is 90s Gundam anime, or more older.

Has 3 teenage boys as main characters. I think one with green gundam was chubbier. They skate to their Gundam during transformation. MC draws a 6edged star(idk what this called) and skate into Gundam. They are always goes around som ruined planet or so(it looked like so from my memory). They also has 1 granny rides magic crystal and 1 bunny girl. Ending theme has endless carrots dancing/bouncing in row. And carrots follows the the bunny girl.
