In this paper we examine an orbit of simply connected wandering domains for the function ${ f(z) = z\cos z+2\pi}$. They are noteworthy in that they are non-congruent but arise from a simple closed form function. Moreover, the shape of the wandering domains, suitably scaled, converges in the Hausdorff metric to the filled-in parabolic basin of the quadratic ${ z^2+c}$ with $c=\tfrac{ 1}{ 4}$, commonly named the ``cauliflower''. We complete our analysis by classifying the wandering domains within the ninefold framework in \cite{ benini+2021}, finding they are contracting and the diameters of the wandering domains tend to zero. To conclude we propose an expansion of the analysis to a wider family of functions and discuss some potential results.
