Mae hafan o liwiau yn gwahodd Rhys a Cerys wrth iddynt groesi drosodd drwy ddrysau glas yr amgueddfa bysgod, hufen iâ yn eu dwylo.

A haven of colors greeted Rhys and Cerys as they stepped through the blue doors of the aquarium museum, ice cream in their hands.

Roedd Cerys newydd ymweld â Rhys am y tro cyntaf ers tro, yn awyddus i weld pa mor dda mae ei frawd yn ymdopi fel tad.

Cerys was visiting Rhys for the first time in a long while, eager to see how well her brother was handling life as a father.

Roedd Rhys wedi meddwl am bopeth: planhigion acwariwm, popcorn, a'r cerbyd babi newydd sbon.

Rhys had thought of everything: aquarium plants, popcorn, and the brand-new baby stroller.

Tra bod Rhys yn gwylio'r morloi'n chwarae, cwympodd y glirdeb yn ei feddwl ac, heb sylwi, fe wnaeth ef gyfnewid y cerbyd babi â un arall ger stondin siocled.

While Rhys watched the seals play, a moment of clarity slipped from his mind, and without noticing, he swapped the baby stroller with another near the chocolate stall.

Fe wnaeth ef drochfa i mewn i sgwrs am octopysau gyda Cerys, heb sylwi'r trap roedd newydd ei osod iddo'i hun.

He dove into a conversation about octopuses with Cerys, unaware of the trap he had set for himself.

"Gwelwch Cerys, mae'r carcharorion hyn yn gallu dianc fel hud!" gwatwarodd Rhys, yn sicr bod y diwrnod yn mynd yn uchel i law.

"Look, Cerys, these prisoners can escape like magic!" Rhys teased, confident that the day was going swimmingly.

Roedd Cerys, hynod o wybodus, yn nodi arwyddion o ffraethineb mewn stori Rhys.

Cerys, keenly observant, noted elements of humor in Rhys's tale.

"Wyt ti'n gwybod bod morloi yn mwynhau cerddoriaeth?" ychwanegodd hi, gan ddal prawf Rhys.

"Did you know that seals enjoy music?" she added, testing Rhys's knowledge.

Yn sydyn, edrychodd Cerys lawr ar y cerbyd acwed, "O Rhys, dydi dy fab ddim eisiau tryweryn eto, dydy?" a chwarddodd bach.

Suddenly, Cerys glanced down at the swapped stroller, "Oh Rhys, doesn’t your son want a stroller yet, does he?" and she giggled lightly.

Sylweddolodd Rhys ei gamgymeriad, ac er bod cydwybod Cerys wedi rhewi, roedd awydd hi dros ddrama yn dal i losgi.

Rhys realized his mistake, and even though Cerys's conscience was frozen, her urge for drama still burned brightly.

Rhys, mewn panig, ceisiodd esgus mai cynllun hir oedd y cyfan, ond roedd hi'n amlwg bod rhywbeth o'i le.

In a panic, Rhys tried to pretend it had all been part of a long-term plan, but it was obvious that something was amiss.

Defnyddiodd Cerys yr eiliad i ddatblygu gweithgaredd a drygioni i'w helpu Rhys.

Cerys used the moment to craft an activity and mischief to help Rhys.

Pan welwyd y teulu arall, a dechrau chwalu'r planhigyn gyda llythyr ping-ogwr oedd yn llawn o don hə., er bod Cerys yn ceisio angau wyllus ei hysbryd.

When the other family appeared, they began to dismantle the scenario with a letter-paper penguin full of humor, though Cerys tried to maintain a mysterious spirit.

Tra oeddent yn arddelio i "'Jellyfish Globyddol" y planhigyn, defnyddiodd Cerys weniaith a gosod y sylw ar y pysgod i sgripiwn Rhywun fuodd yn codi yma.

As they tended to the "'Global Jellyfish" plant, Cerys used wit to divert attention toward someone who had once risen here.

O'r diwedd, roedd y gymysgu drosodd, a roedd Rhys yn canu teimlad bod ei fab saith mis bach yno.

Eventually, the mix-up was over, and Rhys was left feeling that his seven-month-old son was safe.

Roedd Rhys yn chwerthin drwy'r chwarterau dynol-llechfaen, llwyrwybodol am y dryswch.

Rhys laughed throughout the human-stone quarters, fully aware of the confusion.

Gwên Cerys oedd yn tanlinellu pob profiad.

Cerys's smile underlined every experience.

"Drosodd fydd bob amser, Rhys," meddai Cerys.

"It'll be over soon enough, Rhys," Cerys said.

"Ond dyma yw'r gwir gwênau."

"But these are the real smiles."

Roedd Rhys yn camu oddi wrth y cyfandiad cul, llawn o wrth-ddwyster newydd i'r ocsiwn hwn yn ei fywyd.

Rhys stepped away from the tight intersection, filled with a new kind of intensity in this auction of his life.

Roedd ei wddf ymlaen, belen fel gorchestion tri-eiriau a thactegau cydchwarae, gan bwysleisio bod y baste yn ffordd dda o fyw drwy'r oes.

His head was ahead, a metaphor for his three-word challenges and teamwork tactics, emphasizing that the mishap was a good way of living through the ages.

Roedd emerged Rhys gyda dealltwriaeth newydd, bod rhodresiad a chamgymeriadau gwynfyw yn gyflym i roi'r holl sefyllfa aur.

Rhys emerged with a new understanding, that boasting and minor errors could quickly turn into an entire golden situation.

Roedd Cerys yn gweld mwy o barch i'w frawd ac ei habwydnewid.

Cerys saw more respect for her brother and his adaptability.

Ymwelodd y ddau gyda chyfrol lywio a dieithriaeth benodol, a edrychai'n ddigon erchyll i lynu.

The two of them departed with a keen volume of guidance and particular estrangement, looking suitably fearsome to linger.

Pleid mai datganiad oedd y croesdoriad hwn, iawn ar ben ei fywyd wrth i'r donnau chwarae wrth blendid ddreigau cŵl y carchar.

It seemed this intersection was a statement, right at the top of its life as the waves played with the cool dragons of the prison.
