Some of the bigger animals from Pfeiffer's earliest Tipple-Topple moulds have a band of filler round the middle, like a belt.
Applying the filler and tooling it to match the animal's skin or fur must have been time-consuming, and probably added to the selling-price.
With time, the filler usually shrank a little, and shed its paint (and often attracted wood-boring beetles). [You must be registered and logged in to see this image.]
This Elephant shows the filler-belt clearly, and a hole where a beetle larva ate its way out. [You must be registered and logged in to see this image.]
This Rhino's belt has been very neatly modelled, but finished in a furry effect which does not match the rest of his warty skin.[You must be registered and logged in to see this image.]
Even when the paint has stayed in place, you can see the difference in finish between the moulded parts of the animal and the "belt".[You must be registered and logged in to see this image.]
And the same with this Bactrian Camel, who seems to be wearing a girdle of long-haired sheep's fleece.
Maybe each animal was made in two moulds, then fitted together like the halves of a chocolate Easter-egg?
