The Exploits of Moominpappa (Swedish: Muminpappans bravader skrivna av honom själv Literally: Moominpappa's Ordeals Written by Himself) first published in 1950 and then considerably revised in 1968 under the title Moominpappa's Memoirs (Swedish: Muminpappans memoarer), is the fourth book in the Moomin series by Tove Jansson. The story found in this book is mentioned in the previous Moomin books, as Moominpappa writes his memoirs in those stories. Unlike Comet in Moominland and Finn Family Moomintroll, both versions of the novel were translated into English.
Moominpappa has written his autobiography of his amazing life, and he tells it to his son Moomintroll, and to Moomintroll's friends, Sniff and Snufkin. In his tale, he at first was left at an orphanage, but after finding it boring and disliking the strict headmistress Hemulen, he leaves and meets a new friend, Hodgkin.
Hodgkin and Moominpappa meet the Joxter (Snufkin's father) and the Muddler (Sniff's father). Together they build a boat, in which to live. They fool the enormous Edward the Booble into helping to set the ship off. After realising their trickery he becomes very angry, but they sail away. They rescue a Hemulen from being eaten by a Groke, however, the Hemulen is very bossy, and soon they abandon her with the Niblings. One young Nibling stows aboard their ship and travels with them.
They eventually reach a far away land, where they meet the Mymble family. The Mymble's daughter befriends them and together they go to Daddy Jones (the King's) 100th birthday party where they all win prizes. They then set up new homes on an island, however athey re spooked by the island ghost. They manage to make a deal with the ghost, and they befriend him. Meanwhile, Hodgkins has designed the Amphibian - a sort of land/sea ship for Daddy Jones. On its maiden voyage, it is attacked by a giant fish, but they are saved when Edward the Booble steps on the fish.
The Muddler then marries the Fuzzy, and Moominpappa rescues another Moomin and her handbag from the sea. She turns out to be Moominmamma. The story ends and links chronologically with The Moomins and the Great Flood. There is also an epilouge which tells how Hodgkins, The Muddler, The Fuzzy, The Joxter, and The Mymble all visited the Moomin family in the present day.
Moominpappa's Memoirs has been adapted to television four times.
