>>6755679>Redpill me on DUPLO, is it really the best filler? It looks too big to be actually compatible with regular LEGO.I happen to be a bit of a Duplo enthusiast so I can fill you in on the surface-level stuff
That other anon is correct; Duplo fits System at the rough rate of 1:2
Pic related is a Quatro, Duplo, and System brick. As you can see, they all connect.
