The black thing is 4.5cm by .75cm. Maybe too big for a level. It looks like it should attach to something...
The animals do make me think of Noah's Ark, but I don't know what company. Looking at them again, they're painted, and possibly wood. The tails are string. So, definitely not Playmobil, plus the other Playmobil in the batch in 80's and 90's stuff.
