I (had to) made some updates in tagging of certain characters (although not in this particular image). It turns out that four of the kids hanging around the zoo (outside of keepers) are boys. There are two pairs of brothers:

1st pair
Lion shirt boy (previously tagged as Lion shirt girl)
Blue haired boy (no previous tag)

2nd pair (twin brothers)
Topknot twin (previously tagged as Topknot girl;
Bob cut twin, previously tagged as Girl with boyish hair.

I already suspected, that the second pair might be twins, I just didn't know they were boys.

I see the Otter but also the otter.
