Snow Chick, a baby emperor penguin, is the star of BBC1’s one-hour Christmas documentary Snow Chick: A Penguin’s Tale, narrated by actress Kate Winslet.

The production team spent almost a year in the Antarctic, following the young penguin from hatchling to him separating from his parents to go it alone, reports RadioTimes.

If you haven’t met Snow Chick, here’s a brief introduction:

The program aired last night (December 23) in the U.K., and hearts melted nationwide. Snow Chick was the last to hatch and the smallest of the chicks. He tried to join in with the rest of the group, “but it’s hard when you’re the smallest,” says Winslet, narrating the documentary.

Viewers were on the edge of their seat, with some even shouting out loud at the TV when Snow Chick faced dire situations.

Here are some of the emotional tweets that took over the blogosphere:
