Transcript:
A special day for 62 penguins and one sea lion rescued late last year off the Brazilian coast after getting lost during migration.
They've been looked after in a rehabilitation centre and now, after having been tagged, are being released into the ocean to catch a current to take them home.
The sea is choppy but, with a little help, one by one they slip back into the sea.
