Fish kid Harald, piglet Inge, and bird son Philip are almost bored to death. Besides their parents, there is no one around to play with them. Activities like blowing bubbles, frolicking in the swamp, and flying tricks just aren't as much fun alone. How fortunate that the three animals meet one beautiful day and become friends. Harald, Inge, and Philip are completely sure of one thing: There is still so much we can do together.
