I think the basic shapes and colours are often enough of a link to the protected designs they ape, without the need to slavishly copy every detail. Although it is hard to give an opinion based on a detail and not a whole design, I'd suggest moving things around here quite a bit.
Sure, some graphic hints may be enough for most people to catch the reference. But this is stock, and the question is: what will sell better? I'd say: the more obvious.
Anyway, thank you for your inputs. I have definitely changed that speech bubble, a lot.
