We study strange dibaryons based on the SU(2)-embedded {ital B}=2 toroidal soliton. Treating the excursions of the soliton into strange directions as small rigid oscillations, we obtain a good approximation to the bound state approach. We calculate the dibaryon mass formula to order 1/{ital N} and find that the doubly strange {ital I}={ital J}=0 dibaryon is bound by about 90MeV. {copyright} {ital 1996 The American Physical Society.}
