The aim of this paper is to extend the notion of topological entropy for fuzzy
semidynamical systems created by a self-map on a fuzzy metric space. We show that if a
metric space has two uniformly equivalent metrics, then fuzzy entropy is a constant up to
these two metrics. We present a method to construct chaotic fuzzy semidynamical systems
with arbitrary large fuzzy entropy. We also prove that fuzzy entropy is a persistent object
under a fuzzy uniformly topological equivalent relation.
