Yep, caffeine or theobromine were the first molecules that sprung to mind when I saw the bicyclic structure, but of course those two only have nitrogen in the ring system, and the number of methyl groups is incorrect as well. If you keep in mind that hydrogen atoms are omitted, the light blue ones could be nitrogen, then the top one would be part of an imine group. If you take oxygen and nitrogen as the first two heteroatoms, the only one left that would make sense would be sulfur, but I couldn't find any molecule with that combination. Somehow I have the feeling that the animators took caffeine as the base molecule, recolored the heteroatoms and removed one methyl group.
