@Rohin Sometimes "dollar stores" will have the plastic volcano and rocks on the left. The items on the right-hand side are ones I've had for 40 years and I have no idea where they originated.
@snowleopard some of the plants on the right (and the ones in the middle) I have seen in India where they are included in animal toy packs. I believe I may have one or two of the plants on the left.
