In New Zealand, a common chocolate-coated marshmallow treat is the chocolate fish.
A fish-shaped delicacy, 12 to 20 centimeters (5 to 8 inches) in length, it is made of pink or white marshmallow covered in a thin layer of milk chocolate.
The milk chocolate's texture features scale-like ripples on the fish, created by the fish moving under a blower during production.

In Kiwi culture, the chocolate fish is a common immediate reward or prize for a small job done well (e.g. "Give that kid a chocolate fish") so much so that a phrase suggesting a person be awarded one can be said regardless of availability of the treat (and either as a compliment or sarcastically).
