If I can find any I will post pics but for now I can only describe them. There was a set of animal toys from the 90s that each consisted of a small plastic animal that came on a stand with a cardboard back. When you pressed the button on the stand it would make a noise like that animal. You could collect them and attach all the stands together. There were a few different sets each consisting of several animals.
Marine- Giant Squid Great white shark Orca the rest i cant remember
Birds of prey- Lanner falcon osprey bald eagle snowy owl
Savannah- Lion elephant black rhino gorilla(i know they dont live in the savannah but i think it was in that set)
