  We discuss a doubly-holographic prescription for black holes in braneworlds
with a vanishing cosmological constant. It involves calculating Ryu-Takayanagi
surfaces in AdS black funnel spacetimes attached to braneworld black holes in
the $ critical$ Randall-Sundrum II model. Critical braneworlds have the virtue
of having massless gravitons. Our approach should be useful when the braneworld
is a cosmological black hole interacting with deconfined, large-$N$ matter. In
higher dimensions, explicit funnel metrics will have to be constructed
numerically -- but based on the general structure of the geometry, we present a
natural guess for where one might find the semi-classical island. In a
3-dimensional example where a toy analytic black funnel is known, we can check
our guess by direct calculation. We argue that this resolves a version of the
information paradox in these braneworld systems, by finding strong evidence for
"cosmological islands". Comoving Ryu-Takayanagi surfaces and associated UV
cut-offs on the brane, play natural roles.
