"A wild maned sea lion would be a valuable addition to any collection," sighed Samuel Salt, shaking his head regretfully. "But then--" he grinned in his sudden pleasant way, "not much of a mascot at that." The only other happening of note was Roger's capture of a monkey fish. Unable to overtake a flying fish, the Read Bird had pounced on this small combination of a land and water beast as it sat quietly sunning itself on the limb of a tree. Screaming and chattering, he bore it proudly down to the Captain, and Samuel was so pleased with the curious little creature that when Nikobo suggested going back he made no serious objection. And as the hippopotamus, rather weary from her long swim, headed thankfully back for the ship Tandy and Samuel made ambitious plans for the monkey fish's care and comfort. Thrusting it into Tandy's bird cage, Samuel regarded it with increasing enthusiasm and interest. "I'll rig up a wooden tree in one of the aquariums, set the aquarium in one of the large cages so it'll have both air and water, and call it 'Roger' after its discoverer," beamed the former Pirate with a wink at Tandy. "Don't you dare call that monkey fish after me," screeched the Read Bird, flying round to have another look at his strange prize. "Why, it's uglier than a blue monkey, looks like a regular goblin, if you ask me." And to tell the truth, the monkey fish _was_ even uglier than a goblin, shaped like a monkey but scaled all over, and with unpleasant goggly eyes and three short spikes sticking out of its forehead. "It does look like a goblin," agreed Tandy with an amused sniff. "But let's call it Mo-fi, which is short for fish and monkey." "Tip tops'ls!" approved Samuel Salt, taking out his note book. "Wonder what it eats?" "Great grandmothers, what would it eat?" moaned Ato, looking blankly at Samuel. "Another mouth to feed and listen to! Dear, Dear and DEAR!" "Oh, give it a box of animal crackers," put in Roger carelessly. "No, I brought along some gold fish food for just such an emergency as this," declared Samuel, making a little flourish with his pencil as he wrote busily in his journal. "Gold fish food will be splendid for a monkey fish." "Well, don't forget the bananas--for remember it's a monkey, too," chirped Roger, settling on the Captain's shoulder to read what he had written. So, laughing and joking and in the highest good humor the exploring party returned to the _Crescent Moon_. What with planting the slips from the sea tree, settling Mo-fi in his aquarium cage, pressing the leaves from the marine forest, and making copies and further notes about the sea lions in his journal, Samuel did not get his ship under way till late afternoon.
