What's so special about the Fishcake?

Recently I had bought SpaceChem and upon completing all the research challenges, I was able to craft 2 items in TF2 and one of them was the Fishcake. The stats of the Fishcake are identical to the Dalokohs Bar, so is there a difference in what this 2 items can do?

Solution 1:

No, there is no difference, it just looks differently.

There are many "copies" of weapons with different name and look, for example, HHHH and Nessie's Nine Iron act exactly the same as Eyelander.

Solution 2:

No, the Fishcake is simply a reskinned version of the Dalokohs Bar. Both items have the same stats and behave the same way, the only difference is visual. TF2 has quite a few such items, the official wiki has a list.
