Five short lines, one tiny story: a seal arrives with a purpose, finds something better than the purpose, and lingers. Dave Bonta's "Beach bum" is barely a sentence long, yet it turns a scrap of animal behaviour into a small comedy of character.
The title does a great deal of the work. Without it, the lines could pass for a field note scribbled by someone watching the shoreline. With it, the seal becomes a type we all recognise, the drifter who turns up with an errand and then forgets it. "Bum" is a human word, a little rude and a little fond, and it recasts every verb that follows. "Came" becomes an arrival, and "stayed" becomes a refusal to leave. Nothing in the poem scolds the seal, though. The word is affectionate, the way you might tease a friend who has spent the whole afternoon on a sofa.
The grammar carries the joke. The poem is a single sentence, and it changes direction on the small words that join its parts. The seal came *for* the oysters, a preposition that points at a goal, a meal, a reason. It stayed *to* stir sand, an infinitive that sounds just as purposeful but isn't. The syntax pretends the seal still has an aim while the content shows the aim has dissolved. Notice also that the oysters never reappear. We are not told the seal eats them. They slip out of the poem after the third line, replaced by the sand, as though hunger itself had been forgotten.
The word "bed" is the poem's quiet pivot. Literally, an oyster bed is a patch of seabed where the shellfish grow, and the phrase "a good, broad bed" reads like an appraisal of the habitat. But a bed is also where you lie down, and "broad" can describe the seal's own comfortable bulk. The commas in "good, broad" slow the line so that it sounds like approval, as if the seal were testing a mattress. By the time we reach "stayed," the place that offered food has become a place to settle.
The sound of the poem supports this loosening. There is no rhyme, but the same few sounds keep returning. "Seal," "oysters," "stayed," "stir" and "sand" all lean on an s, so the poem seems to hiss and slosh like shallow water. The line "a good, broad bed" ends three words in a row on a soft d (good, broad, bed), which makes it sound thick and heavy, and "stayed" picks up the same sound in the next line. The rhythm is a brisk three or four syllables per line until "and stayed," which shrinks to two. That is the shortest line, and it is the one about not moving. The two dashes also act like small pauses for breath, as if the poem were settling down along with the seal.
The last line is gently physical. "Stir" is a kitchen verb, something done to soup or tea, so the seal's wallowing sounds like a faintly domestic chore. The image is of flippers and belly clouding the water, pushing the sand around for no reason except that it feels good. It is the poem's only picture of the seal in action, and the action is almost nothing.
What makes the poem worth reading is how much it does with so little. It has the compression of haiku, though it follows no counted form, and it gets its effect from one switch of tone, from need to contentment. Behind the humour is a mild, true observation: purposes are often just doorways, and plenty of us have gone out for one thing and ended up simply being somewhere. The poem doesn't moralise about that. It lets the seal stay, and it lets us enjoy the staying.
