The first film by Ugarov has rather "modern" musical harmonies and is the first appearance of the graphic style that would later be used in his excellent "Music Box with a Secret". Though the actual story is pretty similar to his first one in Merry-Go-Round #2. I tried to translate this one with rhyming couplets, but I think it came out a bit forced in a few lines.

The second film by Barinova (Anatoliy Petrov's wife) is a very simple riddle for children (that works better in Russian than in English, because the names of the animals all begin with "ko"). This seems to be the first time she did a painterly art style like the ones she'd later make in the early 1980s, such as "Cat Catafeyevich". Although by itself, her entry is sweet but nothing special - she wasn't yet the mature and visionary director she would become later.

The third film by Petrov is a successful return to a sci-fi theme and realistic style that he'd earlier used in "The Blue Meteorite", and would continue to use later. I quite like this one, only I wish he'd been as imaginative about showing what's special about the plant (e.g. by zooming in and seeing its fine details) as he was with the sci-fi machinery. Though on second thought, maybe it's fine as it is.

The last, by Gennadiy Sokolskiy, is one of the most characteristically "folk Russian" things you're likely to see and just impossible to translate well. I like it, but it definitely works better in the original language.
