Pretty sure it’s a soviet cartoon, and it has this bird character, on long legs, with a long, thin beak, a fluffy body and its eyes are practically sitting on the beak… I got a necklace from my grandma in russia with this bird and i SWEAR i’ve seen it or something VERY, VERY SIMILAR like it in a cartoon when i was younger, but we just can’t remember what the cartoon was! My memory puts the bird to be standing in water, if that serves as a clue, but i might be wrong…
All my previous searches or birds in russian cartoons lead to Kesha, NOT the bird i’m talking about, and my mom suggest that it is the bird from the alien market in the cartoon “The Secret of the Third Planet” (Тайна третьей планеты) that was selling this balloon-like creature, and although the bird IS similar, the beak is too thick and the eyes are part of the beak, while on the necklace they are small (beady?), round and sit right next to the body on the long beak.
Can somebody please help me? My whole family agrees that this bird was definitely in a cartoon (was shown in russia at some point), but none of us can recall this particular cartoon.
Potential leads are also appreciated! =)
