We review the strangeness production data in heavy-ion collisions at energies arround the NN production threshold. The dense nuclear matter environment produced in heavy-ion collisions provides unique opportunities to form strange few body systems. In search for those systems with strong decays special emphasis will be given to $\mathrm{\Lambda }$ p and $\mathrm{\Lambda }$ d correlations. Long lived weakly decaying ligh hypernuclei are accessible by the two body decay into a negative pion and a baryon. Results for p, d, t, ${}^3$He, and $\alpha$ + $\pi$ are reported. The picture will be completed with the discussion of recent measurements of kaon flow over a wide impact parameter range for which comprehensive comparisons with state-of-the-art transport models will be shown.
