Here are a collection of various animals with springs as their tails or trunks in the case of the elephants.  These shakers might actually represent two different series because the second shaker pairs of cats and mice below have different labels.  The first three sets depicted above (dogs, cats, & elephants) all have Norcrest Japan stickers, while the two sets shown below have a sticker that reads "An Enterprise Exclusive Toronto Canada". The mouse above and to the right has no sticker at all, or maybe it just fell off.

The Norcrest sets above have eyelashes, while the Enterprise Exclusive sets below do not.  Otherwise they are all very similar in their color schemes, size, pour holes, and identical springs.  So whether they all belong to together or not, they are fun to collect.
