We observed some unusual changes in Hendelson's original XE037 mouse today.
It increased in weight by over six hundred percent, so we got a dissection authorized.
It had grown a duplicate heart in its pelvis and a new glandular organ that secreted some kind of acidic ooze, it melted our scalpels.
We captured some of the ooze and sent it for further analysis.
It seems XE037 has unforeseen mutagenic properties.
Good thing we're wearing our hazard suits.
