for anyone interested, the loli dragon do NOT speak old english but rather broken early modern english (think shakespear) and no, i am not well read in this matter, it is just a hobby of mine to look things up every now and again when it befalls my interest.
real old english (anglo-saxon) was used around 500 to 1000 CE (common era) and was a completely different language and is more or less incomprehensible without studying it first.
here is a example taken from Beowulf:
Hƿæt! ƿē Gār-Dena in ġeār-dagum,
þēod-cyninga, þrym ġefrūnon,
hū ðā æþelingas ellen fremedon.
this is how old english writing actually looked like, picture taken from a page out of Beowulf:

it was followed by middle english, it was used after the norman conquest around mid-late 1060's, it gradually transitioned to early modern english around 1470~ the transition lasted for nearly 100 years.
next to nothing exist from early middle english days.
middle english 12th century sample, taken from Ormulum:
Forrþrihht anan se time comm
þatt ure Drihhtin wollde
ben borenn i þiss middellærd
forr all mannkinne nede
very early modern english can be found as early as Thomas Malory's Le Morte d'Arthur, printed and released somewhere around 1480-1490, early modern english is however what you see in works made by Christopher Marlowe late 1580's to late 1590's and shakespear 1590-1612.
modern english, as in the one we use today started to come in to use very late 1690's and early 1700's, in between 1710-1720 is where todays modern english fully emerged, but it was not before around 1750's when a dictionary of the modern english was published that the earlier modern english completely disappeared.
shakespear was so important to modern english that it can easily be understood even today, 400 years later, whereas works made by Geoffrey Chaucer and William Langland who shaped the late middle english language is of considerable difficulty to read today without previous study into middle english.
it is somewhat problematic to find a accurate early english translator as they tend to exaggerate, and shakespear did plays, not common grammar structures used day by day.
my advise would be to use one of these two online translators as they are the most accurate ones i could find, others was by intention exaggerated:
