You got your plurals wrong .... words ending in "us"{ like virus, cactus or octopus end in either "i" or "ii" when pluralized. Normally in most "us" ending words the "us" is just switched to a single "i".
Panda - which is short for Pandabear ends in "r" and "r" ending words have an "s" added when pluralized. "A" ending words like panda or banana also get an "s" added when plural.
In short no other words besides "us" ending words tend to be pluralized by replacing the "us" with "i" or "ii".
I want one too

So the plural of panda is pandas, not pandii.
