Free Crochet Banana Slug Pattern


I don’t know. I felt like the world needed a crochet banana slug. He is just so cute I cannot. So here he is. Meet MERVIN, the Banana Slug. Complete with slime trail. Because duh. Haha. Enjoy!

Please always share the link only to this pattern and never the pattern itself. Your visits are critical to me being able to continue to bring you free patterns! Much Love! Stephanie Pokorny/Crochetverse


  • 40 yards light yellow worsted weight yarn
  • 4 yards white and pink fingering weight cotton (Scheepjes Catona shown) OR worsted weight yarn with the plies split in half, using just two
  • yarn for the slime trail, shown is silver metallic fur yarn
  •  sizes B, E, and F crochet hooks
  • black yarn or black paint for pupils
  • glue gun and glue sticks if you choose this method of assembly
  • tapestry needle, scissors, tape measure


While not critical, you do want very tight amigurumi style stitches. There should be no holes. I crochet tightly you may have to drop hook size to achieve this.

Finished Size:

About 3″ long from tip to tail (slime trail not included in this)

Instructions (US Terms):

Main Body:

With F hook and yellow yarn, make a magic ring, ch 1:

Worked in rounds with NO turning and NO joining.

Rnd 1: 6 sc in ring, pull tightly to close. (6)

Rnd 2-4: sc in each sc around. (6)

Rnd 5: (sc in nxt 2 sc, 2 sc in nxt sc) twice. (8)

Rnd 6: (sc in nxt 3 sc, 2 sc in nxt sc) twice. (10)

Rnd 7-13: sc in each sc around. (10)

Rnd 14: (sc in nxt 3 sc, sc dec over nxt 2 sc) twice. (8)

Rnd 15: (sc dec over nxt 2 sc) four times, cut yarn. (4)

Sew any remaining hole closed with yarn tail and weave in ends. 


With F hook and yellow yarn, chain 17:

Rnd 1: sl st in 3rd ch from hook, *ch 3, sl st in nxt ch until 1 ch remains, in last ch (ch 3, sl st, ch 3, sl st), working up the opposite side of the beginning chain in the remaining free loops, (sl st, ch 3) in each ch, st sl to base of 1st sl st made, cut yarn. 

Weave in ends. Either use glue gun or sew the foot to the underside of the body. I positioned the end with the double “ch 3, sl st” end at the fat head side of the body. 


With E hook and yellow, make magic ring, ch 1:

Rnd 1: (sc, ch 1) four times in the ring, sl st to 1st sc made. 

Rnd 2: do not turn, sl st into nxt ch-1 sp, *ch 4 making the last ch loose, sl st in the 1st HUMP (located on the back of the chain) from the hook, make 3 sc in same hump, sl st nxt 3 chs, sl st in nxt sc, sl st into nxt ch-1 sp*, repeat *-* once more, ch 3 making last ch loose, sl st in hump on 1st ch from hook and nxt 2 chs, sl st in nxt sc, sl st in nxt ch-1 sp, ch 3, sl st in 1st ch from hook in the hump and nxt 2 chs, sl st in 1st sl st made and cut yarn. 

Glue or sew the face on the fatter side of the body. The ch-4 sides are the top antennae and the ch-3 sides are the bottom. I positioned it slightly to the side and not directly on front so when I looked at him from the side his face was showing front. 

Eyes (Make 2):

With B hook and fingering white yarn or 2 plies of split white worsted yarn, make magic ring, ch 1:

Rnd 1: 5 sc in ring, sl st to 1st sc made, cut yarn. (5)

Using glue or sewing, affix one eye to the top end of the ch-4 spikes. 

Using black yarn you can sew pupils in the eyes. I used a toothpick and black acrylic paint and just dotted eyes on. 


With pink fingering weight yarn or worsted pink yarn split into 2 plies, sew a small “V” shape mid-face for the smile. 

Weave in any remaining ends.

Sew or glue a few strands of yarn of your choice to the narrow end for the slime trail.
