I've decided to show you some toys which can be useful for 15mm. I took Irregular Miniatures 15mm "FZ103 British Bluejacket in straw hat" from Colonial range for size measurement.
Waterloo Boy toy. Gift from Barry S
Giant Scorpion. Originaly key trinket scorpion from Australian Reptile Park
And repainted version :)
Toy frog from local toy shop.
Toy ferret from same toy shop.
These 15mm gorillas are not toys, but 15mm.co.uk minis from Fantasy range (http://15mm.co.uk/552_Ape.htm)
