Everything is worked in a spiral (except where noted). Use a stitch marker to mark the beginning of rounds, if you don't want to count obsessively. My general amigurumi tips are here.
You can substitute chunky-weight yarn for the DK-weight held double
Rnd 1: Sc 6 into magic ring Rnd 2: Sc into back of stitch around (6 sts) Rnd 3: Sc around (6) Rnd 4: *1 sc, inc* around (9) Rnd 5: Sc around (9) Rnd 6: *2 sc, inc* around (12) Rnd 7: Sc around (12) Rnd 8: Inc around (24)
Rnd 19: Turn, sc4, pick up and sc 20 (ish) sts (24) Rnd 20: *1sc, inc* around (36)
Fasten off.
Head Joining:
Hold heads together side by side, RSs together. Attach yarn and join heads together with 8sc. Immediately begin working in rounds for the Body, below.
Body:
Rnd 1: Sc around (56 sts; now is a good time to do the eyes and stuff the heads with fiberfill) Rnd 2: Dec, sc26, dec, sc26 (54) Rnds 3-9: Continue decreasing in this way, at the midpoint between Elephant and Elephant both top and bottom (you should be able to see the decs on the previous row and work the next decs on top of them) for 7 more rounds. Rnd 10: Sc around (40; finish stuffing body with fiberfill) Rnds 11-13: *sc1, dec* around Next Rnds: Dec every st around until hole in elephant's bottom closed up. Ch 5 to make elephant's tail.
Fasten off.
Legs: (Make 5)
Rnd 1: Sc 6 into a magic ring (6 sts) Rnd 2: Inc around (12) Rnd 3: Sc in back loop around (12) Rnds 4-6: Sc around (12)
Fasten off, leaving a long tail for sewing leg onto Body.
Ears: (Make 4)
Row 1: Pick up and sc 6 sts on side of head Row 2: Turn, inc every st (12 sts) Row 3: Turn, sc12 (12)
Fasten off.
Jaunty Hats: (Make 2)
Rnd 1: Sc 6 into a magic ring (6 sts) Rnd 2: Inc around (12) Rnd 3: Sc in back loop around (12) Rnds 4 and 5: Sc around Rnd 6: Dec in back loop around (6; stuff with fiberfill)
Dec further to close if necessary. Fasten off.
Ch 15 on each side of the hat to make chinstrap ties.
Finishing:
Placement of elephant legs to keep Bimba and Kimba upright.
Attach legs to body as you see fit (or as I, with three in thee front and two in the back). Tie jaunty hats onto elephant heads. Take Bimba and Kimba to see their best friends, Evelyn and Evelyn.
