  Traversable wormholes and regular black holes usually represent completely
different scenarios. But in the black bounce spacetime they can be described by
a same line element, which is very attractive. Furthermore, the black hole
photos taken by EHT show that black holes have spin, so spin is an
indispensable intrinsic property of black holes in the actual universe. In this
work, we derive a rotating black hole mimicker surrounded by the string cloud
(SC), which can be interpolated to represent regular black hole spacetime and
traversable wormhole spacetime. We investigate the effect of the spin $a$ and
SC parameter $L$ on the observables (shadow radius $R_s$ and distortion
$\delta_s$) and energy emission rate of the black hole mimicker surrounded by
the SC. We find that shadow for this spacetime is very sensitive to the $L$,
i.e., the SC parameter can significantly increase the boundary of the shadow.
