We study the possibility of using an experimental spin-1 atomic Mott Insulator with filling-factor one to simulate bosons on a lattice with an infinite three-body contact repulsion, which is equivalent to a three-body hardcore constraint. We map the arising three local degrees of freedom of the ideal bosonic system onto real spin-1 atoms, where a proper fine-tuning of the experimental setup makes it possible to simulate a variety of systems in which this repulsion is present. First, we show that with a rather simple setup the transition between an atomic quasi-condensed phase and a paired one can be studied. Then we propose to use this scheme to simulate a Pfaffian wavefunction, a state arising naturally in the presence of an external magnetic field and three-body repulsion, opening a route towards the study of exotic states and non-Abelian quasi-excitations.
