  We give an explicit description of the minimal regular model of
bihyperelliptic curves with semistable reduction over a local field of odd
residue characteristic. We do this using a generalisation of the cluster
picture; a completely combinatorial object attached to a hyperelliptic curve
$y^2 = f(x)$ over $K$ which contains the data of the $p$-adic distances between
the roots of $f$. We add some information, resulting in a chromatic cluster
picture, and show that this determines the minimal regular model of $Y$ with
the action of Frobenius.
